Wifi transfer rate issues

I've had my macbook pro for alitle while now and at one point i was transfering files to and from the internet using programs like skype with a transfer rate of upwards of 3000 kb/s. but for last few months i havn't seen numbers above 300 kb/s. What happened? is there a way to boost my speeds? ive connected to several different networks that i KNOW are MUCH faster than 300 and it still wont work right. ive looked everywhere i can think to throughout my settings and i can not find a way to improve the performance. can anyone help? get the speeds back to what i feel they should be? im very disapointed in the performance right now.

There are a lot of factors involved with WiFi speed. Noise, traffic on the WiFi network, Traffic on the internet, ISP limiting your speed, site you are uploading to and many more.
Have you thought about connecting the MBP to your router by Ethernet cable and then try these uplaods?

Slow Wireless and Erratic Transfer Rate

Alright, I just got a new Macbook Pro 15 inch last week because my iBook G4 kicked the bucket... again.
All has been well except for wireless. Any Wifi spot has had horrible transfer rates. The TX Rate goes up and down from 54/54 Mbits/sec to 0/54 MBits/sec over and over. This affects local transfer speeds (horribly slow), download speeds and even makes websites not load the first try.
It isn't the router being bad as I've confirmed the problem on more than one router and this is the only computer with the problem on all routers. An Intel iMac with the same (I think anyway) wireless-n card has no trouble at all either with the TX Rate to the same base station.
I tried booting into Windows (XP Professional SP2) but I can't seem to find any utilities to give me as detailed wifi information as AP Grapher does. It was hard to tell if there was a difference.
So is my wifi card at fault here, or OS X? This is a big issue for me and I can't seem to find any solutions online. Also giving a link to AP Grapher to show the TX Rate (the white line) going nuts.

i've got mbp with 10.4.11, that just started SLOWING down madly today..after all the research i see many have it much worse with complete loss of wifi...but this is HORRIBLE
i ran a speed test of IBM laptop side by side with MBP and downstream difference was 3X
HELP!

Transfer rate when moving larger files with MBP +AEBS over 802.11 n

Hi Everyone
I´m very confused about the capabilites of the new AEBS dual band.
I have a Macbook Pro C2D 2,4ghz late 2007 running Snow Leopard , with an airport card N compatible.
Recently i add to my home network an AEBS dual band , and i configure it in bridge mode , with support to the N and G nets.
So when i try to copy a big file (around 2 GB) between the MBP and a FS mounted via NFS, sometime i have transfer rates about 9 to 12 MBytes / s , but after this al the copy´s that y do slow down to 3,4 MBytes / s.
Also i test this copy operation with a 2,5" USB connected directly to the AEBS, and the results are the same , the max rate transfer is 3,4 MBytes /s.
I tried with various radio modes , and different locations (Ireland, etc...) due to the limitation in Spain to use the 5ghz band.
If i look the properties of the connection with de alt button it shows me that the MBP is connected to the N network at 5Ghz and 300 Mbits /s , but the transfers only reach 3,4 Mbytes /s. When i have a G net the transfers reach 2,4 Mbytes / s , i think that i have an limitation in my airport card or a misconfiguration in the AEBS.
Sorry for my English.
Thanks in advance.
Nacho López.

Hi Paul,
The last test is....crazy.
The environment (my home) are the next:
AEBS dual band
MBP connected via wifi N (5ghz)
An old box with ubuntu server 8.10 (Pentium4) with a SATA drive
External USB 2,5" connected directly to the old box via usb.
I perform 2 test , a copy to the SATA drive of the old box, and another copy to the external USB mounted on the old box in the directory /opt/COMPARTIDO/usb.
Here are the results of a scp :
-----COPY TO THE MOUNTED USB-----------------
batman-3:Movies Nacho$ scp -r Ironman\ P1\ \[1080p\]\[AC3\].avi [email protected]:/opt/COMPARTIDO/usb
[email protected]'s password:
[email protected]'s password:
Ironman P1 [1080p][AC3].avi 100% 3334MB 19.6MB/s 02:50
-------19.6MB/S TO MOVE 3,3GB OF DATA IN 02:50--------------
-------COPY FROM MBP TO THE SATA DRIVE OF THE OLD BOX------------------
batman-3:Movies Nacho$ scp -r Ironman\ P1\ \[1080p\]\[AC3\].avi [email protected]:/opt/COMPARTIDO/Mldonkey/incoming/directories
[email protected]'s password:
Ironman P1 [1080p][AC3].avi 100% 3334MB 15.7MB/s 03:33
-------15.7MB/s------------------------------------------------------
So definitly mi issue is not related to wifi N or the performance of my disks. I suspect that maybe the AEBS don´t manage well the protocols like SAMBA (the external usb drive was poor perfomance shared via AEBS) or NFS (the directory shared from the old box also has the same poor perfomance).
If you can, try it, a simple unix scp can makes fly your files over your network.
I´ll continue posting what if discover about this.
Regards,
Nacho.

T530 - Insanely Slow SD card transfer rate

I'm curious if anyone knows why I might be experiencing insanely slow transfer rates from a particular 8GB Transcend SDHC 6 card? If I click on details while it is reading from the card, it will say 'Calculating...' forever. It will take like 5 minutes to transfer 3 - 1MB files. There are less than 200 pictures/videos on the card. The weird thing is that accessing the same card from my old laptop and my wife's laptop works perfectly fine.
And if I take my 16GB Micro SDHC card from my cell phone and put it into an SD card adapter and put that into the SD slot on my T530, no issues, it transfers files at normal speeds?! So it doesn't seem like the reader is bad, it just doesn't like that one card.
Any ideas?

Hi there dudeman,
Are all the card reader drivers up to date?
One of the drivers for the T530 listed here: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?DocID=HT073832 was recent, from August, under Camera and Card Reader. This may not solve your issue but I just wanted to suggest installing the latest drivers if you haven't already.

Gigabit ethernet + TC doesn't mean gigabit transfer rates to the TC drive..

Alright.... I've spent a ton of time trying to figure this out (probably more than I should have) and I thought I'd post my findings so that either a) I'll save someone else time out there or b) someone can tell me I'm a complete moron
So I had an airport extreme. I replaced it with a Time Capsule. I have a Windows (boooo) PC connecting directly to my TC using a gigabit ethernet card (which I bought specifically connect it to the TC) so (I thought) I could enjoy gigabit transfer speeds to the internal hard drive from the wired PC. I had some fun plans of shoving my itunes directory on the TC and letting appletv sync (yes through my pc) and keeping lots of videos there, etc. Who cares - it'd be at gigabit speeds! But, in reality, things didn't quite work that way (though my itunes directory does still live on my TC...for now).
Well, I had a semi-unique situation to do some pretty massive testing because I have 2 gigabit network cards, 1 100mb network card, and a wireless-n network card and two internal hard drives - both very fast. I also tried Cat 5, Cat 5e, and a Cat 6 cable.
And here's what I (think I) figured out:
The hard drive in TC can not achieve gigabit transfer speeds. Your transfer rates will be limited by the IO to the hard drive. In fact, it can't even come close.
Using my "fastest" setup - so Cat 6, fastest internal drive, gigabit ethernet, and transferring a file exactly 1 gig in size I was able to have a sustained transfer rate of 140 megabit per second - that's 17.4 MB/s for folks not wanting to do the math (that's reading FROM the TC. Writing TO the TC dropped the speed down to 106 megabit/second or 13.35 MB/s). Going to a 5e cable knocked that down to 130 megabit a second. Putting in a Cat 5 cable knocked me down to 110 megabit a second. Switching between my two gigabit network cards did nothing. Switching my cards between two computers did nothing.
Now, just changing the above setup to use my 100Mb network card resulted in these results: 67 megabit read (8.4MB/s) and 65 megabit write (8MB/s)...
And using wireless N, I got about 10MB/s up and down.
And just as a final test, connecting my two computers together using the 2 gigabit network cards through the TC, I was able to achieve standard gigabit speeds.
SO what does this all mean?
I think the IO to the hard drive in the TC can only read at about 140 megabit/s and write at about 110 megabit/s. I'm not sure if it's the HD itself or how it's connecting to the TC - but that's why I'm not aware of anyone getting faster transfer rates to the drive in the TC (maybe you guys are?). The gigabit ports themselves are fine - and if you're doing anything from one gigabit port to another gigabit port you'll be fine.
So stop beating yourself up trying to find some elusive XP specific issue with gigabit transfer rates (though vista had a problem - shocker), or that you must have a defective gigabit card (which is why I have two cards now instead of one :)), or that your cable must be bad ("maybe my cat 5e isn't good enough?")... it's just this drive ... or how the drive is connecting to the network - can't handle the gigabit speeds.
Unless someone else out there has another explanation? Do these speeds mesh with what you're seeing in "optimal" situations? Or maybe there's just a throttle switch for goobers like me using Windows instead of MacOS!

Hi,
the interfaces available today which connect your drives integrated electronics to your computer can handle that speeds. but the drive itself is limited by the mechanical things going on in there
You can get such transfer speeds if the data you request is in the cache of the drives internal electronics for example. Some drives have 8 MB of cache memory. So if you request to read or write less than 8 mb and (in the read case) you are lucky enough to have those few megabytes cached then you may get that performance

What is max internal hard drive transfer rate compatible with a 2007 MacBook Pro?

In attempt to upgrade my mid-2007 MacBook Pro (Intel Core 2 Duo), I bought a Seagate 750GB listed as compatible with my computer on MacSales.com . . .
Seagate Momentus XT ST750LX003 750GB 7200 RPM 32MB Cache 2.5" SATA 6.0Gb/s Solid State Hybrid Drive -Bare Drive
Installation appeared to go well and I ran an extended hardware test with no issues found. However, the drive is listed at 5.46 TB (would be nice) and I get an input/output error when attempting to partition. I can initiate an erase, but after the time I would suspect it would take to erase the drive, I get an input/output error - it seems to appear after the first 750 GB of the '5.5 TB' was erased. At all times, the drive is not recognized when I attempt to install OS X from original discs.
I suspect the 6.0 GB/s transfer capacity of the hard drive is not compatible with the MacBook Pro. The drive came with 4 jumper pins but no jumper and no label diagram to set a slower transfer rate. I called Seagate, Newegg, OWC, and Apple, but no one has compatibility info for my MacBook Pro. To them, it appears I am running the first tests of this new technology with an 'older' MacBook Pro.
My MBP has had no issues - I'd like to keep her going with the optimum internal hard drive capacity, but don't necessarily want to set up a test bench in my house (though my kids would enjoy destroying it) and pay several shipping and restocking fees to test new hard drives.
The original drive had a 1.5 GB/s transfer rate. Does anyone know the maximum transfer rate compatible with a 2007 MacBook Pro? 3.0 GB/s? 1.5 GB/s? Thank you.

No spinning hard drive will transfer data faster then 60-80MB a second. The XT models have a flash storage area that is used when reading and writing data that can make it Appear faster in some situations. That flash memory if only 8 or 16GBs in side, I forget which one.
The drie is rated to work on 6GB SATA bus but it certainly can not transfer data that fast. It should be backword compatible to work on slower buses.
Your drive is 750GBs in size. Not wure where you are getting this 5.5TB (that is 5.5 Tera Bytes which is 5500 Giga Bytes. Your drive is under 1TB)
What are you using to partition the drive? Disk Utilities from the original install DVD?
You need to install on your old drive, Update it from the Apple Website then clone it to the new drive. The version of OSX you are using may not function correctly with that large of a drive. Or get yourself a copy of Snow Leopard, retail disk for $29 from Apple, and do all the partitioning and installing with that version od OSX.

Disk data transfer rate - iMac 2013

Good morning Apple fellows
First of all, sorry for my troubled English speaking, I'll do my best to explain the issue I'm having in the best way possible.
Yesterday I finally received my new iMac (I'm a proud Apple user since 2006), the machine has these specifications: 16 GB Ram, i7 processor, nVidia GT 780M, and a SSD drive of 1TB of capacity.
Under Mavericks everything runs smooth and fine, no issues at all, just perfect, the fastest machine I've ever had. Unfortunately, I had to install Windows 7 via Bootcamp (I'm a mechanical engineer and I use Autodesk Inventor to do my stuff).
After completing the installation of the Microsoft OS, I instantly noticed some laggy performance while running Windows: I installed as asked all the Bootcamp drivers with the USB pendrive that I prepared, but both the startup of the system and the normal use were a bit slow, even slower than my old '09 iMac.
In order to understand what the problem was, I ran the system performance test included in Windows: all the ratings I have are maxed out at 7.9 (7.9 is the top I think), in exception of the "Disk Data Transfer Rate", that is 5.9. As far as I remember, this value is typical for a mechanical disk drive, not for an SSD drive supported with PCIe connections.
Does anybody here got a similar issue? Is there any driver package that I have to install in addition to the Bootcamp drivers?
Thanks in advance

That is because the WEI uses your boot disk as the default device to measure performance, and, for instance, a Velociraptor 10 K disk, does not score more than 5.9. The story changes when the test is run on other disks, like my array:
However, this measurement is totally worthless in real life. You should look at practical benchmarks like PPBM5 Benchmark

How to get better than 5.2MB/s transfer rate from USB 2.0 on Mac Mini

G'day,
I've got a circa 2007 Mac Mini with 1GB of RAM, running Snow Leopard. Connected to this is a USB 2.0 500GB Seagate Freeagent drive from circa 2008. As far as I know, the USB disk is free of errors.
I am trying to use dd with a block size of 1MB to transfer a 250GB file from an Ethernet mounted Time Capsule drive to the USB disk on /dev/disk1.
A dd from the Time Capsule to the /dev/null gives me a transfer rate of ~35-40MB/s. However, when the target is /dev/disk1, the transfer rate is only around 5MB/s. I checked the system profiler and disk1 is connected to the USB High Speed Bus.
Any clues on how to improve USB 2.0 transfer performance?

Fragmentation is unlikely to be an issue since I was trying to write to the raw block device with dd which is as close to a pure sequential write scenario as one is likely to encounter (e.g. no small block, random access involved)
From a Linux host, I was able to dd to a file on the disk's file system at 20MB/s.
I'll run some other tests with another disk to see whether the issue is peculiar to the disk or to the Mac's USB subsystem.

Solaris 10 u5 Samba slow transfer rates?

Hi!
I've installed Solaris 10 x86 (Core2Duo - x64) server, with Samba over ZFS RAID-Z. Samba is a part of Active Directory Domain. I've managed to join it to domain, to get the users and groups from A.D. and to translate them to Unix IDs. Everything works really good. Samba is installed from the packages from Solaris 10 DVD.
Only problem I have is the performance :( It's disastrous!
On 100Mbit Realtek NIC, Samba can manage around 4 MB/s if log level is set to very high (10). If I lower it to 0, then transfer rates go up to 7.5-8.5MB/s and they fluctuate in that interval.
On the same network, there is a Debian Samba server, and transfer rates go high as 10.5-11.0MB/s.
Next test I did was switching to Gbit interface. That increased transfer rates up to 25 MB/s, but that is still 5 times slower than the theoretical limit.
So, next thing I've tried was to switch to Blastwave (CSW) Samba instead of SUNW Samba.... My transfer rates went back to normal immediately! It was a bit of shock for me... I could transfer about 10MB/s on 100Mbit interface, and around 45MB/s on 1Gbit interface. 45MB/s is theoretically limit of the workstation hard drive I was doing transfers from.
Sun packaged (SUNW) Samba is 3.0.28 patched today to the latest patchlevel, and CSW uses 3.0.23. I used CSW Samba with the exact same smb.conf file. Only problem is - I never managed to connect CSW samba to ADS on my network :( So I gave up on that, and I'm facing a dilemma. Managers request full speed of the Samba server (comparable to Linux/Windows shares), but I just can't connect to Domain with CSW package.
So I'm asking you guys - any ideas what could be the problem with SUNW Samba and performance? Is it just the 3.0.28 vs 3.0.23 issue, or what? Why is there so big difference in transfer rates? :(
Please help!

OK, here goes my smb.conf:

Clients Connect to N AP's on 5508 and get different Transfer rates than on 4404

I have have 2x 4404's (2x) and 2x 5508's all are running 7.0.240.0. When I take an 1142 and associate it to a 4404 I can connect a test client using N at 144Mbps and I can get transfer rates averaging 70Mbps (using iperf tests). When I take the same AP and associate it to a 5508, (same SSID, etc) I connect at 144Mbps but only get average 6Mbps transfer rates. I get the same results with 1252's. I get the same results if I wipe the config on the 5508 and start from scratch. It only happens when connecting at a/n, when I use a b/g AP such as 1132 I connect at 54Mbps on either controller and get transfer rates of 24Mbps. I have enabled disabled LAG (rebooted), moved the 5508 to connect to the same swtich ports, swapped GBICs. The issue happens on both 5508s, TAC has been unable to resolve this and they are confused as well.
Some of the other things I have tried:
•-          You are facing the issue on 5508's WLC only.
•-          Both the WLC and the client reports high connection speed “144Mbps”
•-          iPerf between wireless and wired showed the following:
on 4400: [124] 0.0-16.9 sec   154 MBytes 76.5 Mbits/sec
On 5500: [124] 0.0-94.3 sec 70.2 MBytes 6.25 Mbits/sec
•-          The AP is the same AP, you just bounce it from 1 WLC to another.
•-          The location of the AP is the same in all the tests, but it can be replicated with an 1142 anywhere on site and get the same results.
•-          The test PC is the same in both cases
•-          The configuration is the same on both WLC’s confirmed visaully in GUI and via CLI outputs and compaired.
•-          The switch is the same, but have tired swapping 4404 and 5508 in data center.
•-          Tried to swap the GBICs.
•-          Used different ports on the 5508 (not just diff GBICs)
•-          Disabled the LAG to rule out the load balancing algorithm.
•-       Replaced the patch cables
Used same ip space that the 4404 is using without sucess.
Upgraded my second 5508 to version 7.5 and exact same resutls.
Any ideas?

Hi
In my 5508 WLC i have exactly the same problem as you gsutherland
I tried apply this command config 802.11b 11nSupport a-mpdu tx priority all disable
and i get message
"802.11b network not disabled"
Why i must turn off b standard ?
Thanks for respons

RAC Interconnect Transfer rate vs NIC's Bandwidth

Hi Guru,
I need some clarification for RAC interconnect terminology between "private interconnect transfer rate" and "NIC bandwidth".
We have 11gR2 RAC with multiple databases.
So we need to find out what the current resource status is.
We have two physical NICs each node. And 8G is for public and 2G is for private (interconnect).
Technically, we have 4G for Private network bandwidth.
If I look at the "Private Interconnect Transfer rate" though OEM or IPTraf (linux tool), it is showing 20 ~30 MB/Sec.
There is no any issue at all at this moment.
Please correct me if I am wrong.
The transfer rate will be fine till 500M or 1G/Sec. Because the current NIC's capacity is 4G. Does it make sense ?
I'm sure there are multiple things to consider,but I'm kind of stumped on the whole transfer rate vs bandwidth. Is there any way to calculate what a typical transfer would be....
OR How do I say our interconnect are good enough ....based on the transfer rate ?
Another question is ....
In our case, how do I set up the warning threshold and Critical threshold for "Private Interconnect Transer rate" in OEM ?
Any comments will be appreciated.
Please advise.

Interconnect performance sways more to latency than bandwidth IMO. In simplistic terms, memory is shared across the Interconnect. What is important for accessing memory? The size of the pipe? Or the speed of the pipe?
A very fast small pipe will typically perform significantly better than a large and slower pipe.
Even the size of the pipe is not that straight forward. Standard IP MTU size is 1500. You can run jumbo and super-jumbo frame MTU sizes on the Interconnect - where for example a MTU size of 65K is significantly larger than a 1500 byte MTU. Which means significantly more data can be transferred over the Interconnect at a much reduced overhead.
Personally, I would not consider Ethernet (GigE included) for the Interconnect. Infiniband is faster, more scalable, and offers an actual growth path to 128Gb/s and higher.
Oracle also uses Infiniband (QDR/40Gb) for their Exadata Database Machine product's Interconnect. Infiniband also enables one to run Oracle Interconnect over RDS instead of UDP. I've seen Oracle reports to the OFED committee saying that using RDS in comparison with UDP, reduced CPU utilisation by 50% and decreased latency by 50%.
I also do not see the logic of having a faster public network and a slower Interconnect.
IMO there are 2 very fundamental components in RAC that determines what is the speed and performance achievable with that RAC - the speed, performance and scalability of the I/O fabric layer and for the Interconnect layer.
And Exadata btw uses Infiniband for both these critical layers. Not fibre. Not GigE.

Network attached storage transfer rates

Can one connect a Network Attached Storage device (Western Digital My Book Live) directly to the iMac via an ethernet cable to speed up the transfer rates? It would only be a one time deal to import all of the data from my device onto the iMac, then I would attach the NAS back to my network.

I too am having similar problems two new Macbook airs yosemite 10.02 and one old basic windows toshiba laptop Toshiba flies Apple sleeps.. I've sent this to the developer of Forklift and WD no response from either. Extremely disappointed with apple. Have I missed something about remounting drives or shared folders or what. If this is standard for apple networking it must be **** on earth for business network users
I have a macbook air yosemite 10.10.2, and a 4 year old windows 7 computer. I run a 4tb WD Nas drive through a Apple Extreme Router operating in Bridged mode. Both Computers are connected via wifi.
When I turn the apple computer on and Open Finder or Forklift I can see both the Airport Extreme and the WD Live Duo Nas drives. When I click on either one in finder it can take up to a minute to see the shares and another minute to mount the shares then a few more seconds to see the contents, once they are visible they can be accessed read and written to quickly as you would expect from a network drive.
In Forklift this process is reduced to about 5-10 seconds much better than finder but even forklift won't reconnect at login.
When I turn on the Windows 7 machine the mapped network drives work and data are attached immediately available, almost instantly as you would expect any network drive to work.
When I turn the Apple computer on The Airport Extreme folder and the WD NAS Shared show in Finder and Forklift but I have to again go through the process of mounting the shared drives again with the same long timeframes applying. I have not been able to find anything in Forklift to have the shared folders reconnect and be ready for use automatically.
I have tried putting the shared drives into user login items but while this works it opens the folder every time and I then have to close them until I need them a most unsatisfactory arrangement.
Am I missing something, or is it just too bad its a mac?

Persistent WiFi/AirPort connectivity issues

If anyone has any input that could help me or perhaps reduce my ignorance, it would be much appreciated.
My Black MacBook has had persistent wireless connectivity issues since I purchased it almost 2 years ago. Even when it shows 3 or 4 bars in my AirPort preferences, it has rather slow page-loading abilities.
For some reason, if I keep selecting my preferred network from my AirPort menu (even when it has NOT dropped the network), that tends to speed up my page load rapidly, but only for a couple of seconds.
It fares a little better when connected directly with Ethernet, but still pretty poor, to the point that I am often mocked by my PC-using friends.
Is there a software update I need? Or a network accessory I can purchase? Or can I replace my built-in wireless card? I am open to anything at this point. Thanks in advance,
K.

Have you tried connecting directly to your router with an Ethernet cable to see if wired performance is significantly better than wireless? I don't see any other inexpensive solutions.
Spending several hundred dollars or more to upgrade your home router and adding RAM and a new hard drive two-year-old computer is certainly cheaper than buying a new computer outright, but it DOES NOT give you any guarantee of the faster online and video performance you seek.
An 802.11 'n' router (with a gigabit wired connections) would probably help connection speed, IF you have a high-speed internet provider with one of the faster DSL or cable services. The fastest 'n' routers provide up to 300Mbit/sec transfer rates, compared with 54Mbit rates for most of the 'b/g' routers, and some higher-end routers (like the Apple AirPort Extreme) support dual band MIMO for multiple simultaneous connections by the same computer, which provides a potential for greater performance. Stop by an Apple store and ask for a demonstration _with your MacBook_ to see if you experience a enough difference to justify the expenditure.
You have to click the "triangle" after the Intel ICH8-M AHCI to see the detailed drive information dropdown. You seem to have plenty of hard drive space available, but I'm guessing you have a 5400 rpm drive. Upgrading to a 7200 rpm drive would help overall system performance some with faster read and write times, but you really don't need extra space at the moment.
Upgrading to 4Gb RAM could also help if you run lots of programs simultaneously, but might not provide noticeable gains for browsing and online video, since you're already at 2Gb.
Of course there is not an upgrade to the GMA 3100 chipset and 144Mb of video ram. It is better than my GMA 950 with 64Mb, but not as good as newer/faster/better MacBook and MacBook Pro models with faster microprocessors and more sophisticated nVidia video chipsets from Apple.

Hanging iMac, slow transfer rates

Hello,
I'm experiencing two problems with my iMac which I think are probably linked as they began around the same time. I've scoured these forums and several other websites for answers but I haven't found many people whose problems sound exactly like mine.
My iMac was running Tiger up until around a year and a half ago. I then upgraded to Leopard without any issues, and everything ran smoothly. About a year ago I began to experience some strange behaviour - Flash would repeatedly crash, my mouse seemed unresponsive, and the system began to hang as though it was having trouble processing things. I reinstalled Leopard and things seemed ok, though the hanging remained (at this stage it was just the umbrella spinning and things taking longer to load). I upgraded to Snow Leopard hoping this would fix the issue when it came out and things got incredibly bad. Starting up and loading to the desktop took upwards of twenty minutes!! Doing ANYTHING seemed to be a massive strain on the system. I'd literally have to spend an hour or so monitoring it just to check my email and shut down in the correct way. Additionally the USB transfer speed, and download speed, had dropped to the point where a 20mb file had an estimated time of 2 hours to or transfer from my external hard drive. Internet downloads were similar.
After as many tests as I could manage I thought it might be RAM related, and upgraded to 3gig. It had no noticeable effect. Recently, whilst trying to solve the problem, I gritted my teeth and backed everything up. I wiped the system entirely, and tried a clean install of Leopard (the last functioning OS I had). It worked, in so far as the catastrophically slow behaviour stopped, but I'm STILL left with the slow transfer speeds, and the hanging. I've since re-upgraded to Snow Leopard, and this time it functions in the exact same way as Leopard.
To describe the problem in detail: Every few seconds - the time between varies from 2s - a minute - the system stops responding for a seemingly arbitrary amount of time. Often the umbrella appears. However, when it appears frozen the dock usually responds without any issues (though is entirely impotent as I can't open anything, including Finder) and if I'm typing then when it returns to my control anything I typed will usually appear. My USB transfer rates remain, even when there's no issue, extremely low. Same with downloads. The most bizarre thing for me is that during the times the system is responding (during which is can often manage multiple tasks without any complaint) it moves and respons in an incredibly speedy, efficient way - as though the RAM upgrade has really helped.
I've tried repairing disk permissions, checking activity monitor to see what may be a strain on the system (everything looks entirely normal), I've run several diagnostics (including tests on the new RAM and the old RAM and on the external hard drives), defragged, turned out absolutely EVERYTHING unnecessary... Nothing I do seems to have any effect on this behaviour! Does anyone have ANY ideas? It's going to be a real pain to get it to an Apple store.
Edit: The reinstallation of an OS, or wiping of the hard drive took between 18 and 24 hours a time, despite it usually showing a countdown from 30 minutes the whole time.

Hello and Welcome to Apple Discussions...
Have you tried booting from the Snow Leopard disk, running Disk Utility and checking the startup disk for errors? If not...
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. Make sure there is always 10% to 15% free disk space
If the startup disk appears to be ok and there's enough free disk space, try running the Apple Hardware Test
If the AHT doesn't report any problems...
experience some strange behaviour - Flash would repeatedly crash
Try uninstalling the reinstalling a new copy of flash then repair disk permissions.
Uninstall Flash
Install Flash

Very slow Ethernet & WIFI transfer speeds - MC340X/A

Hi.
I recently purchased an Airport Extreme model no. MC340X/A being used as an isolated standalone network with 3 gigabit ethernet clients and a couple of n WIFI clients, and no other base station or Hub/Switch in the network.
One of the problems I have is that I'm experiencing very slow network transfers between both ethernet clients and wifi clients of any combination. The maximum transfer rate I can achieve between ethernet to ethernet, WIFI to WIFI, or WIFI to ethernet clients connected to the MC340X/A is 2.5 MBytes / second, on both 2.4 and 5gig bands using n capable WIFI cards and gigabit ethernet cards.
I have performed a hard reset of the device with no improvement.
The firmware is version 7.5 and it appears there is no older firmware to revert back to for this model.
I have an older Airport Extreme n Gigabit model which achieves 7 to 12 MBytes / Second transfers over WIFI and at least 20MBytes / Second over ethernet to ethernet using the same clients, in exactly the same location etc.
Do I have a faulty unit and does it need to be returned? It is only 2 days old and want to sort it out within my 7 day return policy.
Thanks for any help.
Cheers
Cat

Sorry folks, I seem to have worked it out.
I found on another thread that saving the setup info as a profile and re-loading the saved profile has helped some people. This appears to have cured the slow transfers for me so far.
