Start by working out what model you have.
Apple Menu > About this Mac > More info button. Look for the 'Model Identifier'. Also check the OS version that appears in the first dialog.
iMacs from around 2003 cannot run 10.6.8, so something is not correct.
Many things could be the reason for slowness - you need to indicate what is wrong, when it happens what apps are being used.
If you have system disks backup this Mac & run Disk Utility from the install DVD/CD to see if the disk is OK, repair the boot disk. It also helps to remove ALL non Apple USB, Firewire & other devices to see if any attached devices cause the slowness.
It could also be that hardware is failing, so a backup is essential. The original grey install disks will have Apple hardware test which may indicate a fault (or may just report an erroneous message). Record any error numbers & re run the tests several times (issues can depend on temperature). The instructions should be printed on the install disk (normally hold D @ startup with it inserted).
If you have spare external HD's it may be simplest to install a clean version of OS X to see if that boots & is stable. Firewire may be the fastest connection type on older iMacs.
I assume this Mac has been running this OS for a while now? Have you got a full backup of it? How much is installed on it? Are you fastidious about updating software & removing things you don't use?
If any bits are unclear ask & we may be able to dig out links that explain parts of it, but it's important to know the model & OS version accurately.

Your profile was way out of date so the updater I gave you will not be suitable.   This thread does prove the need to keep up to date.
The 4GB is sufficient for your apparent needs though it may be helpful to apply the updater below for the newly advised OS.   It may take some time; it is a biggie!
Mac OS X 10.6.8 Update Combo v1.1   Then check things out.
If that doesn't help check out the number of operations that are running in the background.   If you have the iStat Pro app located in your dashboard, that will help.   It's an excellent app - and free.   See if they're all necessary.
Apple - Downloads - Dashboard Widgets - iStat Pro
Almost certainly others will chip in soon but hopefully I've set you on your way.

My Macbook Pro is running very slowly, what can I do?

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Apps Running Very Slowly

I just got the Macbook 2 weeks ago and have moved all my files. Setup has gone ok, but now when I start using some of the applications they run very slowly - Microsoft Word/Power Point and even Pages act like there isn't enough RAM to keep them running smoothly. Even simple keystrokes in Pages (when it is the only application open) are delayed. This doesn't seem right.
I bought the machine at an Apple Store and had them upgrade the memory to 1G in the store.
Help????

Repairing permissions isn't going to help. If you were having any disk based problem you would want to repair the hard drive, not permissions.
Try a couple of things:
1. Boot into Safe Mode by restarting the computer and after the chime press and hold down the SHIFT key until the startup screen appears (gray screen with dark gray Apple logo and spinning gear) then release SHIFT key. You will get a login window that should say Safe Mode. Run Pages without any other software except Activity Monitor and see what happens.
2. Create a new user account and log out of your normal account and log into the new user account. Do the same as above and see what happens.
This will help determine if you may have a problem with some third-party item that isn't loaded when in safe mode or if you have a preference file, logfile, or cachefile problem when in the new user account.

I have a MacBook late 2008 with OS X Lion 10.7.5 that is running very slowly for the last month

My MacBook is running very slowly. It takes an extremely long time to load an application, to respond to a command, and to quit an application. This has developed over the last month or so. Should I take to Apple Store? A friend suggested that I may need more RAM.

If you have 2GB of memory, that is the minimum required for OS X 10.7 Lion, however, many have found it needs 4GB+ to run reasonably well. Click on the apple on the left of the menu bar, then about this mac, to see how much memory you have.
To confirm if more memory will help, from Launchpad and utilities, load the Activity Monitor. Look at the system memory tab, specifically at page ins and page outs. If page outs is 10%-15% or more of page-ins, you can use more memory for what you run. When the system is low on memory OS X will write the contents of memory to the hard drive to make room for something else to run. Too much of this can impact performance. If you need more memory OWC and Crucial are both quality sources.
Also check your free hard drive space. Generally, you want 10% or more of the capacity to be free for systems usage. If free space gets too low, system performance will also be impacted.

When I add a while loop to the vi "niScope EX Multi-Device Configured Acquisition (TClk)" to acquire data for multiple times, it works but it runs very slowly.

Because I want to acquire the similar data for multiple times and then take an average to increase SNR, I add a while loop to the vi "niScope EX Multi-Device Configured Acquisition (TClk)". It works but it runs very slowly (about 1 sec for each iteration). I think I had put the while loop at a wrong position, which makes the vi run from the very beginning in each iteration. So I really want to know where should I put the while loop to improve the speed? I have attached all the vi and subvi.
Thanks very much.

Dear Zainykhas,
Thank you for posting this to the discussion forums and for uploading some sample code. I took a lok at the issue you have been having, and it is unclear to me as to why you have placed two for loops around the original while loop. My understanding is that you want to use the original Sample.vi and want to execute this N times where N is the Max Freq divided by Interval so that you can scan for a range of frequencies.
Why not just put Sample.vi around one for loop and use the increment counter scaled by the interval to count up towards Max Freq and insert the desired Frequency into the cluster using Bundle By Name?
Kind Regards,

My Mac is running very slowly especially when I am using Facebook and related products. What can I do to fix this?

Hello everyone. My Mac is running very slowly when I am using the internet, and especially when on Facebook. The little rainbow globe spins around for ages before changing pages etc. I have done several virus checks etc, but cannot find anything wrong. Sorry, but I am not tech savvy, so have difficulty with these issues.

Thanks for your reply. Well, I am not sure about the OS X version, I just gave that info from the Install DVD. I have the machine on automatic updates so I guess I am using a newer version. I know it is iMac Snow Leopard and I bought it in 2009. It is the 21.5 inch model. That is all I can tell you. I have 499GB and have used only 32GB, so it isn't a space problem.

My iPod Touch 4 responds and runs VERY slowly, it is probably not even a year old, is restoring it the only option?

My iPod runs VERY slowly, I preordered it when the first white iPods came out. Even typing here it can't keep up, I know if you have less than 6 GB left on your memory it supposedly runs slowly so I deleted stuff and have 13 GB left, I also always close my apps every few hours and my apps always shut down unexpectedly or even before the app can get to the main screen. I do not want to but a new one at all and my dad suggests restoring it and putting it to its original settings but I'm afraid I'll lose my smurfs village and tiny tower. So is restoring your iPod the only way to improve the speed or are there other things?

Try backing up the iPod and then restoring friom backup. See:
iOS: How to back up
If you restore from iTunes backup make sure that all you synced media like apps and music are in your iTunes library since synced media is not in the backup. You iPod will be like it was, included app data like saved games, when the backup was made.

How much free disk space do you have and how much memory do you have, running which operating system? Need that information to have any basis to make recommendations.
