    Welcome,

    First off OS X Lion, alone with no other applications running needs a working minimum of, at least 3-4 GBs of RAM. So, only having 4 GBs of RAM installed is, already putting you at a disadvantage.

    Your iMac model can take a max. RAM total of 6 GBs.

    The extra 2 GBs of RAM may help by giving that little extra RAM for more computer resource hungry applications like Photoshop.

    You can replace one of 2 Gb RAM sticks, already installed, with a 4 GB RAM module for a total of 6 GBs.

    Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).

     

    Another issue is that you are getting close to a having to start cleaning off items of of your hard drive.

    You may want to take card of this now rather than later. So, here are some of my tips for dealing with this inevitable issue.

     

    Hard drive getting full or near full?

    Do a search for and download and install OmniDisk Sweeper and  OnyX.

    Have you emptied your iMac's Trash icon in the Dock?

    If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.

    If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!

    Other things you can do to gain space.

    Delete any old or no longer needed emails and/or archive older emails you want to save to disc, Flash drive/s or to ext. hard drive.

    Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.

    Again, archive to disc, Flash drive or ext. hard drive and/or delete any old documents you no longer use or immediately need.

    Uninstall apps that you no longer use. If the app has a dedicated uninstaller, use it to completely uninstall the app. If the app has no uninstaller, then just drag it to the OS X Trash icon  and empty the Trash.

    Also, if you save old downloaded  .dmg application installer  files, you can either archive and delete these or just delete the ones you think you'll never install, again.

    Download an app called OnyX for your version of OS X.

    When you install and launch it, let it do its thing initially, then go to the cleaning and maintenance tabs and run all of the processes in the tabs. Let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.

    Typically, iTunes and iPhoto libraries are the biggest users of HD space.

    If you have any other large folders of personal data or projects, these should be thinned out, moved, also, to the external hard drive and then either archived to disc, Flash drive or ext. hard drive and/or deleted off your internal hard drive.

     

    Good Luck!

    First, back up all data immediately, as your boot drive might be failing.

     

    There are a few other possible causes of generalized slow performance that you can rule out easily.

     

    • Reset the System Management Controller.
    • 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.
    • Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    • Check your keychains in Keychain Access for excessively duplicated items.
    • Boot into Recovery mode, launch Disk Utility, and run Repair Disk.

     

    Otherwise, take the steps below when you notice the problem.

     

    Step 1

     

    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 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 System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?

     

    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)

     

    Step 2

     

    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 (command-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.

    % user , % system and % idle they all are changing every second going up and down.

    Usual number i see is % user (1.00), % system (.75) and % idle (96.99)

    There is excessive swapping of data between physical memory and virtual memory.

     

    That can happen for two reasons:

     

    • You have a long-running process with a memory leak (i.e., a bug), or
    • You don't have enough memory installed for your usage pattern.

     

    Tracking down a memory leak can be difficult, and it may come down to a process of elimination.

     

    In the Activity Monitor application, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the  Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select

      

    View ▹ Columns ▹ Real Memory

      

    from the menu bar.

      

    If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.

     

    The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.

     

    Another suspect is "Synergy."

      

    If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.

       

    The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:  

    sudo leaks -nocontext -nostacks process | grep total

      

    where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.
