Slower than a snail
Just installed Safari on my pc and man its nothing close to what apple said it should be, would love to call it slow but that would leave you thinking its faster than it actually is. I know the answer is buy a mac but cant even begin to afford one, maybe some day but for now Im left using windows. So did anyone one else have this same problem if so how did you fix it??
Safari seems to consume relatively more CPU attention under XP than comparable applications. Perhaps an artefact of Apple architecture (though not quite of "WordStar port from CPM to Unix" scale).
... wish there was a way to post bitmaps here ... you will have to trust my transcription ...
With all displaying static pages ... the following is a typical (abbreviated) Task Manager process listing
Image Name CPU
Safari.exe 70
firefox.exe 20
iexplore.exe 06
taskmgr.exe 02
BigPond_CM.exe 02
bash.exe 00
thunderbird.exe 00
AcroRd32.exe 00 (now that's a surprise!)
... etc ...

New MacBook Pro slower than a snail
I have just upgraded to a new MacBook, and am having speed issues, first with Mountain Lion and now with Mavericks. It seems as though almost all operations, even selecting a file in the Finder, bring up the beach ball of death, and opening applications like Keynote or Pages can take 30 or more seconds. I am not here to knock Apple, although as a 20+ year user I am disappointed since this is the first time I have ever encountered anything lke this, but I am lost as to where to begin to correct this. Below is the latest EtreCheck output -any suggestions will be gratefully received.

Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long. -
BT sport unwatchable - iplayer slower than a snail
We have a Humax box, with Youview, the box its self isn't that old - fitted less than 6 months ago. We are on BT infinity with decent broadband speed, however, since BT came round and put in the new box, BT sport is unwatchable.
Basically - we can get it, but every minute or so, either the sound goes, or the picture becomes badly pixilated. This doesn't stop - it may be ok for the first minute whilst the chips get themselves sorted, but this just goes on and on.
Also - since the new box went in, iplayer is so slow to load up, we often give up after 10 minutes of watching the circle not going round.
Yes we have turned it on and off again - no I will not speak to their overseas call centre - they are just usless - not their fault, but they can only read from a script, and the scripts are **bleep** - just like BT customer services - yes I have had to ring them in the in the past - and eventually I give up and email the Chief Exec directly - then you get swift replies.
I think the box is sub standard - with rubbish components to save money.
Am trying this way - to see if BT can respond and deal with something, before I send an email to the top.Hi simoncrawley,

Nokia 5800 slower than a snail at sending sms
My 5800 is a waste of time for sending messages, hangs for ages. I've searched forums for advice, found a sms accelerator to download, even downloaded it from the nokia website, an cannot install any of them. Followed every step and advice that people have given with no luck. Not very impressed at all with this phone, for the money it costs the features are poor and the performance is a joke.
I've had no performance issues with my 5800xm at all. It runs fast and smooth and has only crashed about three times in three months.
Quite often problems are caused by 3rd party apps, apps installed on the memory card or corrupt memory cards, which does seem to be quite common with the supplied 8GB cards.
As for SMS sending issues this could be caused by a corrupt card slowing the phone down or an older sim card. Switch the phone off, remove the memory card, switch on and see if it's improved. To test the sim try another persons sim in your phone or ask your network for a free replacement.
Also make sure you are running the latest firmware by checking www.nokia.com/softwareupdate -
Time Machine slower than a snail
Decided to use TM to backup my Macbook Pro internal drive onto a directly connected FW-800 drive. After 12 Hours its done 36 of 88 GB. That's ridiculous! How long would it take to do my 1TB disk at that rate? Two weeks???
When I did my first Time Machine backup (with the same basic configuration) it took my MacBook just over 3 hours to copy 65 GB. Even my current network disk backups take faster. Maybe the disk you're using is bad, or the cable? I really have NO IDEA why my backups across a local FW networking can be faster than your direct backups.
Sorry that I can't be of more help,

Slow as a snail Time Capsule - suggestions please?
I have been using a 1Tb Time Capsule for backing up about 600 Gb of mainly image information along with my main HD for a year or so without any major problems. The drive was full a long time ago but (as I understood it) when new material comes along the oldest backup info is deleted automatically. Yesterday for some reason (after a major Lightroom reshuffle) the backup routine stopped with a message saying "Your backup requires 300 Gb of space but you only have 250 GB (or along those lines).
In the end I erased all on the TC and started again. No problem except the transfer speed has slowed to a snail's pace. Calculating the speed at the moment it will take over 24 hours to backup 490 Gb. Is this correct? The TC is connected by regular ethernet cable, I have a MacPro 2 x 2.66 with 8Gb RAM and 3 internal hard drives. How can I speed up this process? Would I be better off with regular external hard drives connected by firewire?
How come I can download a Compact Flash card of 8 Gb in about 5 minutes and it takes half an hour or so fo the equivalent amount of data to backup on the TC? Thank you.Colin Cadle wrote:

Roughly, yes. It varies greatly, of course, and the first part of a full backup is considerably slower (since the Applications and System folders are the first to be backed-up, and contain hundreds of thousands of mostly very small files). But overall you should get, very roughly, 20-24 GB/hour via Ethernet.
There are a couple of things you can do that might speed it up. See #D2 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
Would I be better off with regular external hard drives connected by firewire?
Oh, yes! With F/W 400 expect roughly 50-55 GB/hour overall; F/W 800 80-85 GB/hour. For a laptop, the convenience of wireless backups is great, but for a desktop, it's a real drag, pardon the pun.

There's a lot more to be done with a Time Machine backup than just copying files. They have a very complex structure, with things extensively linked together so Time Machine can do it's "magic" of only backing-up what's changed, but having each backup be a full one. -
Preview takes forever to open, much slower than on my old MacBook running Snow Leopard. It has been like this since I bought the computer last January. Any ideas?
Take it to an Apple Store for testing. If you don't get immediate satisfaction, exchange it for another one, which you can do at no cost, no questions asked, within 14 days of delivery.

Why is Thunderbolt so much slower than USB3?
I'm considering two different drives for Time Machine purposes. Both are LaCie. Either of these:
- Two Porsche 9233 drives, 4 TB each
OR
- A 2Big Thunderbolt drive, 8 TB, which I would configure as RAID 1 (a mirrored 4 TB volume)
My question is this: I've viewed both of these product pages via the Apple Store, and I noticed that LaCie's information for the Thunderbolt drive makes it a lot slower than the USB drives. Meaning: They say that the 2Big Thunderbolt drive maxes out at like 427 MB/s, whereas the Porsche USB drives max out at 5 GB/s. Why is this? Isn't Thunderbolt supposed to be a lot faster than USB (any iteration)?Not an easy question, short of a whole lot more detail on the construction of those two devices. You're likely going to need to look at the details of the drives and probably at some actual data. You're really looking for some real benchmark data that you can compare, in other words. Particularly which (likely Seagate) drives are used in those (IIRC, Seagate bought LaCie a while back), and what the specs are.
The hard disk drives themselves are a central factor, where the drive transfer rate is a key metric for big transfers (and that can be based on drive RPM as much as anything, faster drives can stream more data, but they tend to need more power and run hotter), and access (seek) time for lots of smaller transfers (faster seeks mean faster access, so good for lots of small files scattered around). Finding the details of the drives can be interesting, though. I've seen lots of cheaper disks that spin very slowly, which means that they can have nice-looking transfer times out of any cache, but then... you... wait... for... the... disk... to... spin.
The device bus interfaces can also vary (wildly) in quality. I've seen some decent ones, and I've seen some USB adapters that were absolute garbage. Some devices have decent quantities of cache, too. Others have dinky caches, and end up doing synchronous transfers to hard disks, and that's glacial compared with memory speeds.
One of your example configurations also features RAID 1 mirroring, which means that each write is hitting both disks. The writes have to pass through a controller that can do RAID 0 mirroring, and that can write the I/O requests to both drives, and that can read the data back from (if it's clever) whichever of the two drives is best positioned in related to the sectors you're after. If it's dumb, it won't account for the head positions and drive rotation and sector target. Hopefully the controller is smart enough to correctly deal with a disk failure; I've met a few RAID controllers that weren't as effective when disks had failed and the array was running in a degrated mode. In short, RAID 1 mirroring is a reliability-targeted configuration and not a performance configuration. It'll be slower. Lose a disk in RAID 1 mirroring, and you have a second disk with a second copy. If the controller works right.
If you want I/O performance without reliability, then configure for RAID 0 striping. With that configuration, you're reading data from both disks. But lose a disk in a RAID 0 striping configuration and you're dealing with data recovery, at best. If the failure is catastrophic, you've lost half your data.
But nobody's going to make this choice for you, and I'd be skeptical of any specs outside of actual benchmarks, and preferably benchmarks approximating your use. Reliability is another factor, and that's largely down to reputation in the market; how well the vendor supports the devices, should something go wrong. One of the few ways to sort-of compare that beyond the reviews is the relative length of the warranty, and what the warranty covers; vendors generally try to design and build their devices to last at least the length of the warranty.
Yeah. Lots of factors to consider. No good answers, either. Given it's a backup disk, I'd personally tend to favor eliability and warranty and less about brute speed.
Full disclosure: no experience with either of these two devices. I am working with Promise Pegasus Thunderbolt disk arrays configured RAID 6 on various Mac Mini configurations, and those support four parallel HD DTV video streams with no effort. The Pegasus boxes are plenty fast. They're also much more expensive than what you're looking at. -
URLClassLoader slower than system loader
I'm subclassing URLClassLoader to load jar files on the local file system. I noticed that URLClassLoader loads about 30% slower than placing the jar files on the system class path. In my app, class loading performance in very important -even though it is just a one time hit.
I suspect the URLClassLoader (which I believe is implemented mostly in Java on Sun's VM) is not leveraging the many performance optimziations that the system loader enjoys (which is probably implemented in native code).
I also experience the same performance issue if I try to do jar loading myself using Java ZipFile i/o.
Comments?well there is quite more overhead involved - loading from classpath of course is the most optimized one.

Home Hub 3 is slower than dial up.
I used to be on a voyager 220v router but started having connection problems. After speaking to customer support, and after they ran some tests on the line/router, they told me that the fault was with the 220v and as it was obsolete, i would need to change to a HH3.
After receiving the HH3, im now finding that the d/l speed for webpages is slower than it was on dial-up. Ive tried running speedtester but it fails to complete and just gives an error that it cant be completed at this time and to try later. After reading another thread on this issue, i went and found the settings from the hub itself, these are posted below:-

is their anything amongst the above which explains why its running so slowly?Bah, this is a PITA.
Got up around 7am and the HH3 was displaying connection time of 10 hours, great, lets leave it for 24 and see what happens. Tried browsing and pages were incredibly slow to load, thats when they did actually load. I said stuff it and took the dog for a walk and left everything as is. Got back and checked again at 9.15 to find a connection time of 14 mins, so obvioulsy something has reset itself.
Tried speedtester and quite simply, the page would not load in order for me to test it.
Tried clean line check, sounds perfect, no noise whatsoever on it.
Tried connecting to the test socket and now get the following results:-

I have my Mac Book Pro with the OS Yesomite since a month and I am feeling that my mac is getting slower than before a month. I want to install OS Lion on my mac. I think i have a DVD of OS Lion which comes when i bougnt Mac laptop in 2011. Should i install OS Lion? What wil happen if i install OS Lion, do i lost my Applications or ...????
Hi, the last install dvd that came out for mac's was Snow Leopard,10.6.3. Lion is a download from apple. You cannot just install it over Yosemite. You would have to backup your drive to save files you want and do a clean install. You might want to look into getting more memory. You can run 8 Gig"s of memory on your Macbook Pro.If your Macbook Pro is getting really slow you might want to download EtreCheck and then post the results here.http://www.etresoft.com/etrecheck Check out this article. http://support.apple.com/kb/PH19031

Mac OS internet 5x slower than Windows 7 on BootCamp
Alright, here is my problem...
My one and only computer is a mid 2010 iMac... I recently moved to a new place. Prior to me moving I was stuck with an awful 3Mbps download speed. (You can tell how much I hated it by looking at my username) Now that I moved, I am able to get much faster internet. So, I got a plan that offers up to 50Mbps download speeds (Xfinity Blast cable internet). I didn't want to rent my ISP's modem/router, so I purchased my own. I got a Motorola sbg6580. As soon as I got everything hooked up, it seemed perfect. I used speedtest.net to see what I was getting. I first tested on Windows 7. To my surprise, I was getting around 70Mbps. I then restarted my iMac into the Mac OS to do some speed tests. On the Mac OS, I was getting around 50-60Mbps. A bit slower than Windows 7, but still very good. The next day I decided to do a "real world" test. I downloaded a 1 Gigabyte file just to see how fast it was. Now, if I was getting 50Mbps the file should have taken just under 3 minutes to download. Instead, it took around 7 minutes. I figured it was maybe just the website I was downloading from. (the file I was downloading was the Cry Enginge SDK - http://www.crydev.net/ ) I did some research and discovered the website testmy.net - I am not sure if this is completely reliable or not, but every test I do on testmy.net I get around 10Mbps. At first I thought it was my ISP ripping me off, then I decided to do a testmy.net test on Windows 7 via BootCamp. (please note that on both Mac OSX and Windows 7 I did multiple tests over the coarse of multiple days) On Windows, I could instantly tell that the test was going much faster. The results for testmy.net on Windows 7 were 50-60Mbps. I did not completely trust the website, so I downloaded the same Cryengine SDK on Windows. It took around 3 minutes, just as it should have. I researched a bunch online trying to find info on this problem. I tried many "solutions" but none of them changed anything. (these include but are not limited to: Tried different DNS servers, Disabled ipv6, disabled sbg6580 firewall, disabled mac osx firewall, tried changing the wireless channel, and reset sbg6580. I came to the conclusion that it was the sbg6580. I thought that maybe an airport express would give me better results. So, today I bought an Airport express. With the sbg6580, I was able to disable the router features so it was just a modem. I was then able to set up the Airport express as my router. It fixed nothing. I am still getting the same results, Windows is still getting anywhere from 50-60Mbps while Mac OSX is getting around 10Mbps. I am out of ideas, if anyone could please help me that would be great. Also, if you need to know anything else please let me know. I may have missed something...
A quick note:
At my old house I had my iMac hooked up to a surge protector. For maximum internet performance, my iMac was connected to my router with an ethernet cable. During a bad storm one day, a lightning bolt either hit my house or very close to it. Ever since, my ethernet port has not worked. I have tried multiple eithernet cables as well as multiple routers and networks. I do not have the money for apple to completely replace my logic board. - So anyway, I am unable to test the performace with an eithernet cable.
Extra information:
My sbg6580 as well as my Airport extreme are both sitting on the same desk as my iMac, so it is obviously not a signal problem.
I also own both a iPod touch 5th gen and a iPad 2nd gen. I am getting around 20-30Mbps on both of them. I am not sure what would be a "good speed" on either of these, but I figured that was pretty good for a tablet and ipod.
The upload speeds on both windows 7 and Mac OSX are around the same 5-10Mbps.
I am using Google Chrome on both Windows 7 and Mac OSX but, I have also tried Firefox and Safari.Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
Flash player 10.1 slower than 10
At least, that's how it is on my secondary computers. On my Dell Inspiron B120, flash 10.1 latest is like a train wreck when it comes to playing Youtube videos in full screen. Disabling hardware acceleration helped a little, but this shouldn't be happening as I uninstalled 10.1 and installed an archived version of Flash 10 with much better playback AND with h/w acceleration enabled. The laptop uses XP SP3 and Firefox.
Simply put, Flash 10.1 feels a lot slower than 10 on my Dell laptop (1.4 GHz celeron-M, intel 915g video, 512 mb ram)
And there's another odd but minor problem I seem to be having with is flash animations on my main computer and any other computer/laptop I have using Flash 10.1. I get this alternating 'lag' every few seconds; it's like the computer is dropping frames because the CPU can't keep up. I could completely understand this, but this is happening on practically any flash animation I throw at the computer. I just tested a flash movie (SWF format) on my main computer (2.8 GHz AMD Athlon x2 240; 2 gb ram, Windows 7 x64, Firefox) and I get this irritating choppy lag here and there. Again, with the previous Flash version 10, I did NOT have this problem AT ALL. Everything was silky smooth; the only benefit I'm getting from Flash 10.1 is x264 hardware acceleration for my ATI Radeon 4200 HD. Before anyone asks, all of my computers were using the latest flash version AND video drivers prior to these tests.
I am VERY frustrated with these problems as I've posted a similar thread twice now in the past. No one seems to be answering or helping me with this; Those that do reply simply claim that they're having the same problem.
Adobe, please look into this problem. Eventually Youtube and several other sites will force me to upgrade my laptop to Flash 10.1.Has Adobe fixed the problems with version 10,1,82,76 of flash player ?
I compared it and found nothing but problems.
I then uninstalled 10,1,82,76 and rolled back to 10,0,12,36 which works fine on Firefox and Opera but I can't install 10,0,12,36 on Exploer or Chrome
it keeps telling me there is a new version even when I try to install it from local drive with a archived version.
With all the complaints about 10,1,82,76 and the lack of response from Adobe on any fixes I will not be using Adobe auto updates until I let some
other poor guinea pigs suffer all the bugs and problems first.
You would expect a large company to have better development and testing before imposing buggy upgardes on us. -
