Strange Slow Down OSX 10.4.x

Has anyone experienced this and solved it?
I am having a strange problem. The system slows down until it eventually requires a reboot.
It can see the problem the worst with PHP/Webmail application(s).
However if I do a "time which ls" when there is an problem; it is 8 times slower than after a reboot. I have tried turning off all services and waiting; then restarting. The problem will persist until reboot occurs.
I am using a Software Based RAID 0 configuration on a G5 dual processor Xserver.
I have read something about turning off Write Cache but have not found a place to do so.

There isn't enough information in your post to answer the question.
You need to look at various stats on the server to work out what's going on. First things to check would be CPU load and memory utilization. Given that you're running a PHP app I'm going to hazard a guess that you have a memory leak, but it's not possible to tell from the current details.
Next time you get into this state, use /Applications/Utilities/Activity Monitor to see what's going on. Look for processes with high CPU usage or memory footprints.
Only once you've pinpointed where the problem lies you can start to focus on actual problems and fixes.

Strange slow down

ok, so i'm trying to wrap my head around how this happened. i opened fcp and it loaded all my open projects at a normal speed.
than i quit fcp and had to do a file transfer. i've two macs hooked up via ethernet and started transferring files. none of these files are in any of my fcp projects.
i opened up fcp during the file transfer, and it took like ten minutes to load just 1 project. it was massively, ridiculously slow. so i quit fcp, stopped the ethernet transfer, reopened fcp and it loaded at normal speed.
how and why did the ethernet transfer slow down the opening of fcp?

Not only that, but FCP on startup scans mounted drives for footage/renders. If your remote drive is mounted FCP will wander off looking there. This is exasperated by the bandwidth occupied by the copy in progress...

Will OSX Mountain Lion slow down my computer?

I have an iMac (about 2 years old) and was wondering if OSX Mountain Lion will slow down my computer.
Computer Specs
=================
Processor: 3.6 GHz Intel Core i5 (1 Processor with 2 cores)
Memory 8GB 1333 MHz DDR3
=================
I'm not sure what else could be useful, so tell if there is.
Thank you

Sorry I wasn't sure which to click (Lion or MT Lion) since I was asking about Mountain Lion but had Lion...
Anyway, Thanks

HT1338 My imac OSX version (10.6.8) has slowed down tremendously, what can be done clean it up? Should I bring in to an apple store for am evaluation? I think my comoputer is laden with virus.

Mu IMac pc haa slowed down so much . It takes so long to open up all of my files. Should I take it in to an Apple store? Do the stores staff who can repair computers that are contamiinaed from virus? I tried PCmatic.com but their progam is not meant for imacs. I can/t open up the download.
Is there another online stie that cvan help me?
Thanks!

Not enough free space on the startup disk can slow the system down.
Control click the MacintoshHD icon on your desktop then click Get Info.
In the Get Info panel you'll see: Capacity & Available
Make sure there's at least 15% free disk space.

My iMac 8.1 was slowing down and had permissions problems. I backed everything up, and then re-installed. Now all I get is a black screen. Power+D gives me a hardware error message: HDD-1336. Help!

My iMac 8.1 (10.6.8 ) was slowing down and had recurrent permissions problems, mostly with Java. I backed everything up, and then re-installed from time machine. Now all I get is a black screen which says I need to reboot. Power+D gives me a hardware error message: 4 MOT/1/40000003: HDD-1336 or HDD-1327. When I reboot from the OSX CD and start disc utilities everything checks out OK. When I reload 10.5.2 from the OSX CD everything seems to work OK and no more permissions problems. But then I loose all my email and safari stuff. Anyone have any ideas short of going back to my old PC?

Hi
Thanks for the help. No point in fooling around with it any more. Will I be able to use it as a monitor if I get a mimi mac?
Cheers. Don
No unfortunatley it's too old, you are referring to Target Display Mode which became avialble in 2009, your 2008 needs to have the HD replaced. I'd still do that if everything else is OK or you can simply buy a new MM and display or even a new iMac or an Apple refurbished iMac to save money.

MacBook Pro 13" Late 2011 Experiencing Significant Slow Down After Boot Camp Installation

     Okay, so today, after installing Windows 7 on my MacBook Pro via Bootcamp Assistant, I experienced significant performance slow down (fans going at full blast, applications opening after extended periods of time, keystrokes not being registered) when I returned to my OS X partition/second hard drive. I have dual hard drives, one of them being a Samsung 256 GB SSD with OS X Mavericks and the other being my original 500 GB HDD, divided into a 250 GB OS X Mavericks partition and a 250 GB Windows partition. I have the SSD set as my startup disk and I have it located in the main HDD bay. I moved the old HDD into a caddy and placed it where the optical drive normally should be.
      After multiple failed attempts to install Windows via USB and Bootcamp Assistant, I decided to reinstall my optical drive and use a Windows installation disk. This attempt proved successful, and I was able to install Windows 7 onto the 250 GB partition I had created for it on the 500 GB HDD. After completing basic setup of Windows, I removed the optical disk drive and reinstalled the SSD and the HDD into their original spots (SSD in the main HDD bay, HDD in the caddy where the optical drive normally is).
     After completing this tedious process, I booted my Mac back up using the SSD. However, I noticed something was wrong when the login screen, apps, and nearly everything else on my desktop had slowed to crawl. I decided to check my Activity Monitor to see what the problem might be. Activity Monitor told me that the task "kernel_task" was taking up anywhere from 200-600% of my CPU, which explained the slowdown in performance. I looked around to see if there were others with the same problem as me, and I found that Spotlight Indexing might be an issue, with a potential remedy being move my Bootcamp Partition into the Privacy section of Spotlight under System Preferences. After doing that, I experienced no increase in performance and everything was still going very slowly.
     The next step I took was to see if booting into Safe Mode would help the issue. After booting into Safe Mode on my SSD, I noticed that things were back to their normal speeds, with applications opening at the speed they should be and keystrokes being registered instantaneously. However, the fans were still going and had not shut off once booting into Safe Mode. In addition, I checked Activity Monitor and the "kernel_task" in question was no longer taking up massive amounts of the CPU.
     At this point, I don't know what to do and I need help in restoring my Mac to original speeds. I may end up deleting my Boot Camp partition as a last measure if all else fails, seeing as I installed Windows in the first place for running a few programs and games that I can live without. However, I'd prefer to not have things come to that and fix things before deleting the Boot Camp Partition. I've heard that if everything runs normally in Safe Mode, then the issue is third-party software. Is this true?
     Any help would be greatly appreciated as I am writing this from the MacBook in question in Safe Mode because it's essentially useless in normal SSD operation.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

External monitor slowing down my MacBook pro

I recently hooked up a brand new external Acer G205HV monitor to my 15" MacBook Pro (4gb RAM) using the mini display port to DVI adapter from Apple. I have an GeForce 9400M graphics card with 256mb ram. Whenever I have the monitor plugged in it slows down my computer tremendously. When I do not use the monitor, my laptop is back to being lightening fast.
Expose` and the dashboard lag a ton, and basically the internet craps out. I can barely load websites and streaming video has become virtually impossible. I have tried running with the laptop open and in clam mode. Same result. At first I thought I had a virus, which would be very very rare, but after using the laptop without the monitor I realized that the monitor was slowing me down.
The max resolution that I am running the monitor at is 1600x900 @60Hz. The DVI adapter is supposed to support a much higher resolution than this. Is my graphics card the issue? Any help is appreciated. thanks!

I have the same problem with a spring 2008 MacBook (4,1) with 4 GB RAM running 10.5.8. Using a DVI external monitor, the wireless speed drops by at least half and usually more. This is the case whether using a Samsung 2443 BW at home or a Dell at work. I've tried different DVI cables, changing channels from 11 to 1, no difference.
Took it to the local Apple store where they had only a VGA monitor to test with and, strangely, the wireless was unaffected. It was a small ACER monitor, a 15-inch or so, not wide-screen. Have had no other opportunities to try a VGA monitor, as I don't have a mini-DVI to VGA adapter.
But I wonder if there's something there?

My macbook slows down after using external HDD

When I use an external drive via usb, my computer really slows down giving me no choice except reboot.
I watched memory usage with activity monitor. Free memory decreases by time and inactive memory increases with the same amount and others don't change much. If I continue using -esp. reading-, free memory comes below to 100MB and then increases a bit -I think it starts paging =other applications' memories= to system disk-, then continues to decrease. Closing the application -that use the external- do not relese memory from inactive to free but ejecting the external does. After unplugging and trying to use the other applications, I face very sluggish performance so that rebooting becomes a better-fast choice. Both NTFS and FAT partitions produce the same result and I don't have any other partition.
If I try to re-read the same file after the external drive stops spinning (sleeps), it does not start spinning but trying to read another file makes it start spining. This makes me think about some -overdone- caching problem, but don't know what causes it and how to turn it off (Tuxero's caching is already disabled in the preferences, although I think it is only for writing only).
I made some research and found nothing specific; they tell to reinstall the os or format the drive -to HFS+ -. What is causing this?
Note: All of my drives are in Spotlight's exclusion (privacy) list and using another usb slot did not change a thing.

System slowed down after Mavericks update (10GB RAM)

Hi,
I have recently updated to Maverics on my mac pro, 2 x 2.8 GHz Quad-Core Intel Xeon, 10GB RAM.
When I perform regular tasks it's all normal. Unfortunately I do some much more than that. I use Aperture on a daily basis and it seems to have slowed down a bit. The issue is more apparent when I use Final Cut. I can't have any other design/photography/video software on the background anymore. My computer can't deal with. But it could before Mavericks! It will also complain about not enough memory when rendering...
I understand that kernel task is heavy on the memory and after an EtreCheck I also realised how much memory spotilight is using. I already excluded a lot of items from spotlight, and it's way better, but still, why is my computer so slow?
Please can someone look at my check and tell me if there's anything I can do to boost my system back to it's previous glory?
thank you

Beware of perceived RAM use. 10.9 uses RAM more efficiently:
About memory management in OSX 10.9 Mavericks
Memory is managed differently, and more efficiently in 10.9. It is (mostly) unique in the industry, but may become trend.
Let’s start with the basics. Mechanical disk drives are very slow, with access speeds in the 10s of milliseconds and transfer rates in the 200-400 Mbps range real world. SSDs are much faster, on the order of a couple of ms access and typically 1200-3000 mbps transfer rates. RAM is much faster than either, in the nanosecond access and transfer speeds of ~8 Gbps effective (1 GHz x 8 bits/byte).
These are rough numbers for comparison purposes only.
So the goal is to keep as much in RAM as possible. But if you run out of RAM what do you do?
Traditionally you take the least used RAM and write it to a special part of the disk, in a way that you can access it most efficiently - minimizing the disk delays. This is called a swap file because you swap RAM in and out of it.
10.9 has a new trick: it compresses RAM using the main processors. Rather than swapping stuff to disk (disks are slow), it actually uses the processor to compress memory and make, for example, 1 GB of physical RAM hold as much as 1.5GB. Similar approaches are used to make MP3 files 10x smaller than the real thing - there is redundancy in data and you can take advantage of that. Apple is making the following calculation: the processors can compress way faster than the disk can swap. And its also predicting that the processors are often partly idle - waiting for swap files or disk access. So rather than swap files around, its compresses the files ***in RAM***.
Compression works,. Tests show that on average it is faster, and that 4GB (i have 4 GB RAM) acts like 5 1/2 - 6GB. Wow.
So, 10.9 will load up most of your RAM, knowing that it can compress some when it needs to. So don’t worry too much that it may look like all your RAM is taken - yea, it is, but its OK.
The measures to look at are:
1. amount compressed. Compression means it has run out of RAM and needs more. As long as compression is low this is fine. In fact this is how 10.9 uses RAM more efficiently than 10.6,7 or 8. Contrary to common wisdom, it requires LESS RAM than 10.8. The colored indicator tells you who this is going - green (good), yellow( iffy) and red (bad).
2. amount swapped. Once it cannot compress any further, or can’t do so efficiently, jot begins old-fashioned swapping. This is a major slow-down and means you would benefit from more RAM. Tiny amounts are OK.
here's an article by Apple - but on th pre-10.9 memory management techniques....mostly still true, but read on.
http://support.apple.com/kb/HT1342?viewlocale=en_US
Bottom line - compression makes 10.9 use RAM more efficiently than previous OSX versions. It also makes the “ram used” indicator less meaningful, and mans you should monitor “compression” .
That said, RAM has always been one of the most cost effective upgrades possible. People spend too much on new machines and too little on more RAM.
Hope this helps,

Slow down issue with Premiere CS4 on a Mac pro

I am having a similar slow down issue with Premiere CS4 on a Mac pro, but I don't have bloated prproj file size.
Here is what I am working with:
Mac Pro intel quad core 2.8ghz
OSX 10.6.7 Snow Leopard
6Gigs RAM
3TB storage between 4 drives, each drive with about 50% free space
I am editing a 10 minute HD video from avchd files. The edited video is very heavy in photoshop files with a variety of different fx including green screen. The system has slowed down to almost a standstill. Anytime I move the playcurser, or try to do any action, it displays the spinning top "thinking" icon and takes 15 seconds to several minutes to unfreeze. I am often forced to force quit and I have gotten unexpected quits several times. The program also freezes on startup frequently.
No other programs are running. When I export with media encoder, it took about 4 hours to complete. The last 4 or so photoshop images I added seemed to tip the program over the edge. It had been slowing down some, but those last few really dropped the processing speed. Before those additions, export took 30 min to 1hr.
I did delete the render files (did not check if the file size was bloated beforehand, oops) but it has not significantly affected my performance.

Do you need all of those extra pixels in the stills? Are you panning the full 4976?
Two things to consider are that if you using, say a 1920 x 1080 Sequence Frame Size, you can only see that at any time, regardless of how large the images are in pixels. If there are extra pixels, i.e. the Pan is not using all 4976 pxls., I would Scale to just what you need in PS, prior to Import.
If you are doing any Scale in PrPro, its Scaling algorithms are not as efficient, as those in PS. [Note: CS5 and 5.5 are a major improvement on that statement.]
With many large stills (the max for CS4 is 4096 x 4096, if there ARE extra pixels, pushing those around will use up resources, and quickly. As a test, some years back, I was working on a "photo wall," and was using 4000 x 4000 images. The workstation had no issues with slowness, until I got to the 5th large still. By the 8th, the Project was too slow to edit. I had to wait for everything. Luckily, I have AE, and it handles large stills much more efficiently, and much differently, than PrPro. I just moved to an AE Comp, and completed the Project, finishing up n PrPro, after I Exported from AE.
Just something to think about. With Scaling in PrPro, this is one time, where bigger is not necessarily better.
Good luck,
Hunt

Slow down after scanner attached

I have been scanning photos with the HP scanner that Apple gave away with the computer.
Everything I scan is followed by the pinwheel spinning for four to five minutes before anything goes back to normal. Is this 200GB computer full already? Not even close, so why the slow down?
Thanks,
Mike

How full is the hard drive? How much memory is installed?ave you launched from an OSX install disk and used the Disk Utility to repair permissions on the hard drive?

IMac slows down wifi/LAN cable connection

Hello,
I came across a quiet unique and annoying problem, that I have not seen being discussed so far.
I spend the last 3 weeks trying to solve my internet/wifi connection following all kinds of posts here.
Problem: Wifi/Lan internet connection is slow (less than 0.8mbit/s)
Problem only appears when I login with an iMac via wifi OR lag cable
iMac, 2011 27`` Mac OS 10.7.5
Background:
I have a 20mbit/s internet connection with my provider. works fine on iPad, iPhone, appleTV HTC one mini, etc… BUT as soon, as I login with my iMac, the internet connection slows down to less than 1 mbit/s
I have tried following solutions:
- live box (router) was exchanged and is brand new
- security settings on router changes (wpa2 etc)
- all channels on router tested from 1-13
- keychain saved passwords for Wifi and router deleted, PRAM reset
- renewed lease of connected devices (no IP conflict)
- shut down wifi on iMac - connection with all devices great, as soon as i switch wifi on, all devices lose their high speed connection and go down to less than 1mbit/s
- connected iMac via LAN cable: same problem, all speed is lost
- iMac is not in the network - speed is great
- connected iMac via time capsule wifi, same problem. connected iMac via netgear extender, same problem
also, if I open network preferences and start the "assist me" app and run diagnostics, all dots are green except the ISP and server, bit most of the time they switch to green immediately, but connection is still slow.
Reception bar is on "3", so signal strength is no problem, and I´d like to emphasize that this is also happening on LAN cable. and again, if the iMac is disconnected from wifi AND / OR LAN, all other devices work fine.
Would love to hear your thoughts!
Thanks!

Although I have been on Mac OS for a while now, I have never had to troubleshoot faulty network in the mac itself.
OSX does apparently have a safe mode boot..
OS X: What is Safe Boot, Safe Mode?
Try that.. as that gives you the same thing as windows with all the extras left out, so you get a basic operating system only and you can see if the problem still exists.. if it does.. I would simply bite the bullet.. wipe the Mac.. reinstall the OS and then carefully reinstall your applications from original disks/downloads and move your operating files back .. but start a different user on the computer and copy back the min you need to get working again.
If the problem still happens even in safe mode boot then do a hardware test.. because it is possible something has actually failed at the hardware level.

Mac to mac copy slows down over internal airport network

This is a strange problem but here goes...
Some useful background info:
I have recently downloaded through the new Airport Express network I just created a file that was 212MB from a site on the internet in about 12 minutes or so which is pretty fast for a DSL connection.
The issue:
When I try to copy files from a PowerBook G4 running Leopard 10.5.2 to an iMac G5 running the same version of the OS, I see the same odd behavior (copying from Public folder to any folder on the iMac):
The copy starts in the finder just fine and seems to be going very fast as expected by an internal network copy but after some arbitrary amount of time, the copy slows down and eventually fails. The time to complete the transfer starts out really fast and eventually hits a brick wall where it slows down further and further.
Other notes: the copy I've been attempting is files and folder that are about 1GB total but I've tried it with small and large copies and this has worked fine in the past with Leopard and other OS'.
Sometimes, this slowdown occurs at 5MB into the copy, other times it doesn't happen until it gets about 50MB into the copy. Thew strange thing is, large files over the Internet are just fine as I mentioned above.
There's plenty of free space on the machine that I'm copying to but this happens repeatedly when I try to copy from one computer running Leopard to another.
I don't think this issue is related to the Airport Express because I recently created a new network to test this issue called Bedroom Airport Express. Previously, when I'd been successful performing these types of transfers, I was using the LinkSys WRT54G's built in wireless capabilities and had no issues using Go To and entering the computer's IP address.
When this issue started to occur, I was baffled so I hooked up the extra Airport Express I had lying around and I'm still seeing the same issue despite the Internet transfers working like gangbusters.
The router is still the WRT54G on AT&T's DSL network using DHCP and there's no special config., other than that I had to re-IP the internal network to 192.168.199.1 for work related reasons but that's about it.
The MTU had to be increased to 1492 for the internet to work properly when I got my first WRT54G [an older version of this device that I replaced very recently with a new one]. The firm ware version of the router is v8.00.2 and the Airport Express has been recently updated to the latest firmware available (and this issue was occurring before the firmware upgrade as I added the Airport Express as an troubleshooting method).
Does anyone know where I should begin to try to resolve this issue? I've tried LinkSys tech suppport and I still get "we're not able to provide Mac tech support" reply despite the fact that addressing the router is done via a webpage and the BSD guts under the hood. If anyone knows what if anything I can do to troubleshoot what the issue is, I would greatly appreciate the assistance.
This networking stuff is a bit of a black art to those of us that are dilletantes in this arena and I certainly qualify as a dabbler in this stuff.
Thanks in advance,
<DM/>

I'm new to the Apple discussions, although not new to Apple computers and I've seen that this post has received quite a few views but no responses. Maybe someone could direct me to the right place to post this, if this is not that place, or, suggest some terminal tools that I could use to troubleshoot the issue with the Airport network or LinkSys Router I'm using [WTR54G v.8.0.0.x]? Thanks in advance for any assistance anyone can provide to a networking noobie.

A lot of us have iBooks that are slowing down.

What iBook do you have? Memory? CPU usage? OS? Etc.
I purchased my iBook in January of this year. 1.42, 14", 512 memory.
It ran so fast. Faster than my 1.25 Power PC G4 at work! I installed Tiger a few month or so ago and now it's running much slower than it did. I've reinstalled the OS, removed CS2 and Dreamweaver (since they were the last installed), verified and repaired disks.
After updating to 10.4,2, system profiler now says "CPU Speed 1.33" even though it is 1.42. ???
CPU
Photoshop has 32.80, Safari has 3.5, Itunes 1.9
147mb of inactive memory.
I have 44.05g free on a 80g hard drive.
Only thing connected is a bluetooth mouse.
I'm going back to the Genius Bar tomorrow. I'm extremely upset that my iBook is running so slow.

I purchased my iBook in January of this year. 1.42, 14", 512 memory.
If you purchased your ibook in January your CPU speed is in fact 1.33ghz. The latest speed bumps from 1.33ghz to 1.42ghz on the 14" happened in July of 2005. Try repairing disk permissions and optimizing the disk to see if that helps. (Run a program like Onyx, Cocktail, or MacJanitor to do this or do it manually) Another user went as far as purchasing DiskWarrior (which is not a bad idea) to repair and optimize his HD and found that the 'peppiness' returned.
With 512mb of ram you will probably notice a larger slow down than on a machine with 1g. 512mb is the minimum amount of ram that is recommended for running OSX.

Completed all Troubleshooting steps but continue to get slow downs from unresponsive scripts on Firefox. Is there a way to use my browser w/out slow downs?

Mac OSX.
I've gone through the list of troubleshooting tips for slow downs and for unresponsive scripts. I continue to get slow downs to my computer and browser when I use my Firefox. It is becoming so bad that sometimes I cannot get work done.

And now, I think I've identified part of the issue. When you pin tabs as an app tab, this slows down Firefox in all the ways I mentioned. Please, please Firefox, if you are going to offer such a useful and simple thing, make sure that it works...
Having closed these App Tabs, I had a temporary break from the slow downs... Then after another few minutes, the slow downs in Firefox continued... At my wits end.
