8900 Bluetooth transfer very slow ?!

Hey there, i hope some1 can help me, few days I got BB 8900 , and i bought Trust Bluetooth Adapter, when I install drivers for bluetooth it was normal sending ( normal speed ) I transfer song (5Mb) in 10 sec .. but now when in try 2 transfer song it took me about 6-7 hours .. is it problem with transfer speed , i saw that somewhere on my BB or my laptop, but i cant find it now can some1 tell me is that because that speed, or something alse.. If its because that, can some1 tell me where can I change that.. 10x

Also a problem with the speed of the bluetooth transfer of BB Bold.
I paired the Bold-9700 with a Nokia XpressMusic to transfer some photos -- very slow transfer.
Tested the speed between Nokia and a PC -- satisfactory fast bluetooth transfer.
Tested the speed between the BB and the PC -- very slow bluetooth transfer.
So I ruled out the problem in the Nokia and in the PC. There might be sometihing I have missed in the settings of the BB bluetooth, that helps it work smootly. Can someone give any ideas on what can fix the problem ?
P.S. I completely rule out the idea that RIM have designed the BB Bold 9700 with such a poor bluetooth capabilities

Data transfer very slow on mac pro!! mac H/W unable to fit specifications.

Hi,
I am installinginternal disks on the quad mac pro and the transfer ratet in the mac are very slow!!!
the disks are: barracuda 7200.10 disks, 500 GB. Sta II 300, max ST3500630AS firmware 3.AAE . throughput:300mb.jumpred off to get the 300.
MAC tells that the QUAD MAC Pro equipment (2x2.66ghz dualcore intel xeon) comes with a 3.Gigabit specification/ 300MB/sec. (Intel ESB2 AHCI, speed: 3.0 Gigabit. AHCI version 1.10 supported)...
And the benchmarks of the disk ST3500630AS show maximum 80MB/sec and a minimin of 37.3MB/sec, average 63.1 MB/sec. (anandtech tests).
According to seagate.com the maximum sustained data transfer rate:78MB/s
but in the mac the reallity is different: I am getting a transfer rate of 22MB/sec!!!!! . with out any application running and only making copy of the files!!!!
that means that the mac is only providing only 1/3 of the expected transfer rate for the disks..
so, is there a way that the MAC Pro gets all the normal transfer rate for those disks???
Is the Quad MAC Pro hardware unable to get the maximum throughput of the disks???
It seems that the mac is unable to get also the average transfer rate of those disks.. how to correct it???
thanks a lot
Alberto
ps. just for fun: I am getting a faster transfer rate from an old power pc ,and old pc, and firewire 400 and old ide disks!!! (36MB/seg!!!)

Yup.
BThe latest Mac Pro are better, so if you have a new or 2 month old unit, Seagate should work, though I think there should be later firmware.
Some would say those drives take the cake or woRSe.
http://www.barefeats.com/hard91.html
SEAGATE PUZZLES
+Firmware version 3.AEE or later solves the slow sustained large block write speed issue for a single 7200.10 inside the Mac Pro.+
+The remaining performance issue is slow small random read speeds for one, two, three or four drives. No matter how many drives you configure in RAID 0 sets, the average random read speed for combined block sizes from 64K to 1024K is less than 30MB/s (based on QuickBench 3 testing).+
+Until Seagate fixes this, we can't recommend the 7200.10 series as the ideal boot drive for the Mac Pro (or Power Mac).+

File transfer very slow with a SSTP VPN

I have a serer in the office and I connect from my house through a SSTP VPN. In my home computer (client) I add a new network folder, this networkf folder is in the server, that has a shared folder. I can transfer files, but is very slow.
For example, to transfer a folder that contain about 20 files, and in total are 11MB, it takes about 3 minutes. The server has a upload bandwidth of 890kbps. With teamviewer VPN takes about 1minute with 55 seconds.
The problema with the SSTP is that the transfer speed is not stable, bteween 0-200kbps. The problema is that when has to transfer a file, always the same, the speed drop to 0bytes/s and in this state is about 1-15 seconds and continue the transfer. Why?
So the total time at the end it's much more than the time that I need if the connection was stable and used all the bandwith. How I say, teamviewer VPN takes about 1:55 inteado of the 3:00 of SSTP.
Thank so much.

Hi ComptonAlvaro,
Please check if we have other program is connecting the Internet when we use the SSTP.
Additionally, we could contact the ISP to check the stability of network.
Regarding the slow SSTP performance issue, we could refer to the following thread similar to this issue.
http://social.technet.microsoft.com/Forums/en-US/8e8e4220-af25-4627-bed2-47db8c04d318/sstp-and-slow-transfer?forum=winserverNIS
Please take the following steps to fix this issue:
1. Add new registry key and value “ TcpAckFrequency=1 ” for all NICs on VPN server, so that we can reduce ACK delay.
2. Disable Windows 2008 SNP feature, and restart VPN server
3. Disable TCP Checksum offloading on VPN server
Hope it will be helpful.

E3200 USB storage - transfer very slow

Hello
The E3200 transfer rate I get is approximately 2.5MB/s ,
That seems very slow, especially with the n configuration, the USB3 hard drive I attached
Is there a way to improve this?
P.S..
I'm using the latest firmware 10.0.03 (build 9)
Thanks

Sorry, but what you write is inconsistent and confusing.
First you wrote 2.5 MB/s and 6 MB/s which means megabyte per second (which is the rate you usually see in Windows Explorer). That translate into 2.5*8 = 20 Mbit/s or 20 Mbps which is megabit per second. There is no "spare" and no "overhead" in this calculation. Transfer rates only count the contents bytes transferred and don't include overhead or anything else.
It's a fact that with a wireless connection rate of 54 Mbit/s you can expect transfer rates of approx. 20-25 Mbit/s.
I suggest you look at it again:
1. What is the connection rate shown for your wireless connection?
2. When transferring files, what is the exact rate shown?
Because I am pretty sure if you carefully look at the units of those rates you'll see exactly what I have posted before:
with wired you get transfer rates of approx. 6-7 megabytes (MB) per second i.e. 48-64 megabit per second (mbps).
with a wireless 54 Mbit/s connection you'll see about 2.5-3 megabytes (MB) per second, i.e. 20-24 megabit per second (mbps) because that's the maximum transfer rate to be expected on a 54 Mbit/s link.
If you had really wired transfers with a rate of 5.4 Mbps, i.e. 5.4 megabit per second that would be very bad in any respect.

IChat song transfer VERY slow

Sometimes when my friend (who has a 2.0ghz iMac G5) tries to send me a song iChat to iChat (approx. 4Mb in size), the file transfer is very slow (one song would take about an hour). I have a 1.2 Ghz iBook G4. The weird thing is that sometimes it is slow and sometimes it works really well. Also, whenever i send my friend a song, it goes really fast (even at the times when sending songs to me is really slow). Does anybody know ways to make the file transfer speed faster?

The speeds of your machines really have little effect on the time it takes to transfer file. It all depends on the network and the connections between the two computers.
It can be a variety or problems from congestion, to the packets taking a longer router due to congestion, peak hours, etc.
So the question is, where is the file being transferred from and where is it going, as well as what type of connection does each user have? The closer the distance and faster the connection, the faster the file transfer (in most cases).

Time machine file transfer very slow during OSX 10.7 re-install

I am using a macbook pro, and was running 10.7. (not sure exact version, and cannot look now, but should have been up to date) I tried the free upgrade to Mavericks, but it failed and said I had a disk error. At this point I could not boot back to 10.7 so I booted with apple-R. I tried to do a repair from disk utility but that failed so I erased my hard drive. Then I proceeded with an install of 10.7, which proceeded fine. I got to a point where it asked about transferring files, (forget the exact wording) and I said to use my time machine backup (from right before I tried the upgrade - backup was 80GB) and I started that. It has been 16 hours and it still has not finished. The external hard drive (Lacie) clicks / whirs, and I see signs of very slow progress... (seems to be at about 80% now judging by the progress bar) but it can go hours without any noticeable change. The "time remaining" information is variable -- going up and down -- and is clearly not correct-- has said 1.5 to 2.5 hours for the last 12 hours
Any ideas? should I just wait a few more days   should I abort and restart the file transfer (if so, what is the best way to do this?)
I cannot provide details on the computer since it is still busily restoring (I hope), but it is roughly 3-4 years old, lots of free space on hard drive (>100GB),

Log and Transfer Very slow

I am just curious if it always takes a VERY long time to log and transfer clips? I moved the files off of my SDHC cards and onto my hard drive. It's about 55GB of 1920x1080/60i footage. From a Sony HXR-NX5U/NX5N. And on average it will take a 5 minute clip about a half-hour to 45 minutes to transfer into FCP. Is this a normal thing?

Not normally, no. But the NXCam cameras employ yet ANOTHER flavor...non-standard flavor...of AVCHD. This makes importing slow and difficult. I had good luck with clips 5 min or less, but longer...and it would take from 2-5 hours!
The solution is to use a third party application...ClipWrap2. www.clipwrap.com
The good thing about that solution is that ClipWrap will import the timecode from the camera...because it does have timecode that it records. But FCP...AVID...they can't find it (Sony likes to hide things apparently). But ClipWrap found it.

IPad Photo Transfer Very Slow....???

I'm using my IPad as a spare hard drive / memory chip to store all my vacation videos and photos then transfer them all to my PC in one go when I get home - the only (well, the main) problem is that the transfer rate is extremely slow. Is this normal ?
I'm using a macbook pro with USB2 and a fat iPad cable, and transferring in Win7. (Tried image capture in osx, it said "there was a problem" and simply stopped the import part-way through)
My other problem is that all the photos & videos are stored on the ipad in many different directories. If I search for *.jpg or *.mp4 to group-copy all the files, it won't let me copy them.....I have to copy the contents of each directory individually....
There must be a more straightforward / quicker way than this ?

I am not sure where movies shot with camera or video camera go. I am assuming they would all go into the Photos app on the iPad.
Have you tried just syncing your iPad the normal way in OS X?
Normally, if you have photos in the Photos app on iPad, iPhoto in OS X is supposed to open and it will ask you to import the photos to iPhoto from the iPad. I believe the same is true of the video. If video is stored in the Photos App on the iPad, it should sync and copy to the iPhoto app on Mac OS X.
Once imported, you can always access the original by going to your iPhoto library and either copy the data to a new location for editing (if using different photo editor) or for video, copy those to a new location for video editing, say, in iMovie, or some other video editor.
And I agree with the previous poster, leave the images stored on the cards that it writes to so you will always have an additional backup source of photos or videos in case something goes awry when you try to use your iPad.
The iPad is not really meant to be a portable, mass storage HD just to store tons of content for dumping to a computer later.
It's more a light applications/multimedia, ereading type of device. There are new portable HD's and WiFi portable HDs that you can have connected to an iPad for mass storage use.
Look at ones by Hyper Drive, Seagate or Western Digital.
Anyhoo... Try a normal iPad sync to see if it transfers normally instead of using Image Capture.
See if this works.
And yes, the transfer rate maybe slow, especially if you shot a lot of video and depending on the resolution you shot your photos in.
Good Luck!

Bluetooth keyboard very slow on Pages

Is there any patch or fix for the extreme slowness using the Bluetooth LB with Pages? It's at the point where it's nearly useless.

Hi and welcome...
Try new batteries and try restarting your iPad.
Press and hold the Sleep/Wake button until the red slider appears. Slide your finger across the slider to turn off iPad. To turn iPad back on, press and hold the Sleep/Wake until the Apple logo appears.

Wireless File Transfer VERY Slow

Might not be the right forum but does anyone have any idea how to set up the wireless connection to be very fast? I thought it was something to do the 54mbs?? Is it something I need to change on all the macs?

No b clients just one mac plugged directly into the
router via ethernet cord, and then my powerbook which
connects wirelessy... to copy a 20mb file it took
10mins...
Which router do you have?

Very slow transfer speeds with external hard drives through Firewire and US

Hi All,
My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little. Apple support suggested I post my issue here. Just to make a note, I measured my disk speeds with both AJA System Test and copying files between drives and reading the Disk Activity in Activity Monitor.
I have 3 external drives, all MyBook Premium or Professional, 1x 500GB, 1x 1TB and 2x 1TB in RAID 0. I had them on Firewire 400 and the RAID 0 2TB one on Firewire 800. My transfers on FW were all around 24MB/sec on all drives (much less than what I should be getting with FW400). I then read somewhere that the FW bus on the MacPro uses the slowest speed connected for all FW connections. So I unplugged everything but the FW800 Raid 0 drive and my transfer rate jumped to 40-60MB/sec. This is much better, but still about half or so of what I expect it should be producing from an external RAID 0 setup.
To keep my FW800 backup drive faster, I've plugged the other two into USB2.0. The transfer speeds on both drives are now hideous, around 10-15MB/sec. This is so slow, but I'm not sure what to try to fix my speeds.
The HD's in the external drives are all 7200rpm, and all should be transferring at a higher rate. Do you have any suggestions or ideas? Ideally I'd like to get everything transferring at rates they should be transferring at, but I'll settle with my current FW800 speed of 40-60MB/sec if I can get my other two drives transferring at a non-snail pace.
Is this a common issue? I can't believe I'm the only one plugging multiple external hard drives into their Mac Pro. I hope someone has a fix or solution for this. I'm all ears!
Thanks in advance.

Hi Kappy, thanks for the information.
So I rejigged my setup a tad. My RAID 0 is still FW800, the second drive is back on FW400 on the back port, and the third is USB 2.0 on the back as well.
It's interesting to note that I saw the FW800 taking a bandwidth hit if the FW400 drives was being read/written to. For example, if I was averaging 50-60MB/sec on the FW800 drives and copy something large to the FW400 drive, each drive averages out to about 30/MB second, roughly half the FW800 speed I was getting. The USB while the slowest didn't cause any slowness on the FW drives.
Here are my Xbench results. These results are from each drive being benchmarked individually with no other drives being tested at the same time.

Very slow transfer to Time Capsule (Ethernet)

I am trying to transfer 80 gb to my Time Capsule (Ethernet) but transfer is very slow (100 kb/s). How can I fix it?

Plug the TC into the Computer by ethernet and make sure the computer shows the link is running at gigabit.. if not replace the cable.
Turn off wireless.. there should be only one data path.. ethernet.
Turn IPv6 to link local only in the computer network setup for ethernet.

Internal Disk to Disk Data Transfer Speed Very Slow

I have a G5 Xserve running Tiger with all updates applied that has recently started experiencing very slow Drive to Drive Data transfer speeds.
When transferring data from one drive to another ( Internal to Internal, Internal to USB, Internal, Internal to FW, USB to USB or any other combination of the three ) we only are getting about 2GB / hr transfer speeds.
I initially thought the internal drive was going bad. I tested the drive and found some minor header issues etc... that were able to be repaired so I replace the internal boot drive
I tested and immediately got the same issue.
I also tried booting from a FW drive and I got the same issue.
If I connect to the server over the ethernet network, I get what I would expect to be typical data transfer rates of about 20GB+ / hr. Much higher than the internal rates and I am copying data from the same internal drives so I really don't think the drive is the issue.
I called AppleCare and discussed the issue with them. They said it sounded like a controller issue so I purchased a replacement MLB from them. After replacing the drive data transfer speeds jumped back to normal for about a day maybe two.
Now we are back to experiencing slow data transfer speeds internally ( 2GB / hr ) and normal transfer speeds ( 20GB+ / hr ) over the network.
Any ideas on what might be causing the problem would be appreciated

As suggested, do check for other I/O load on the spindles. And check for general system load.
I don't know of a good GUI in-built I/O monitor here (and particularly for Tiger Server), though there is iopending and DTrace and Apple-provided [performance scripts|http://support.apple.com/kb/HT1992] with Leopard and Leopard Server. top would show you busy processes.
Also look for memory errors and memory constraints and check for anything interesting in the contents of the system logs.
The next spot after the controllers (and it's usually my first "hardware" stop for these sorts of cases, and usually before swapping the motherboard) are the disks that are involved, and whatever widgets are in the PCI slots. Loose cables, bad cables, and spindle-swaps. Yes, disks can sometimes slow down like this, and that's not usually a Good Thing. I know you think this isn't the disks, but that's one of the remaining common hardware factors. And don't presume any SMART disk monitoring has predictive value; SMART can miss a number of these cases.
(Sometimes you have to use the classic "field service" technique of swapping parts and of shutting down software pieces until the problem goes away. Then work from there.)
And the other question is around how much time and effort should be spent on this Xserve G5 box; whether you're now in the market for a replacement G5 box or a newer Intel Xserve box as a more cost-effective solution.
(How current and how reliable is your disk archive?)

Very slow network transfer (AFP, thunderbolt, nas, gigabit, lan, lion)

Hi,
When copying large files (100GB) from my macbook air to my Qnap NAS the transfer is very slow (100kB/s). It becomes immediately much faster (10MB/s) when I lock my session.
The MBA is connected via the gigabit port of the thundrbold display and a gigabit switch to the gigabit port of the NAS.
There is negligible other network activity shown when monitoring NAS or MBA bandwith usage.
So what can limit bandwith of a mac while in unlocked session?
Is the a bug in thunderbolt display dramtically deminishing bandwith when used? Bandwitdth is already high when locked and display shows login screen. It does not need to fall asleep.
Thx

I want to thank you for your help but I think I have to give up. I've been trying for days to get the MBP just to recognise the NFS share. I've tried adding a server in Finder with no luck. I tried Directory Utility with full R/W access setup on NAS, then tried accessing root NAS folder, then the specific share folders, then with specific user enabled on the specific share folders but whatever I try I get nothing. I've changed my local username and password and UID on the Mac to exactly the same one I use for my NAS but it still won't find it and none of the command line options that people suggest do anything at all. I've tried SMB and AFP but they're both sluggish and nowhere near the performance of XP on the same hardware. For an OS that supposedly 'Just Works' I've had a very complicated, tedious and fruitless experience (pun intended). Maybe it's just me because others seem to report no problems accessing their NFS shares or transferring at high speeds with AFP or even SMB but I've had no luck whatsoever. Very frustrating indeed.
Again, sincere thanks for your time and I'll tag the post as answered because for all intents and purposes you answered my question very well. Unfortunately, this Mac just doesn't like me and I don't think I'll be spending money on one anytime soon.
