Frequently, the classic environment monopolizes the system. This makes the whole OS feel sluggish, because the the Window manager is trying to tear through all its code while sharing a huge number of resources with Classic. This happens on a lot of Unix platforms, and Windows as well. Unlike Windows, Unix and OS X provide a fine-grained way of alleviating this problem. It is called "renice". This command line tool wll allow you to finely control the priority of every program running on your system, including Classic. Typing "man renice" at the command line can give you detail descriptions of this tool, but I'll walk you through the basics (read the rest for the details...)
1.Start up a terminal app and create a terminal window, if one isn't created automatically.
2. At the command line type "ps -x" to list all your processes. You will get output that looks like:
509 ?? Ss 16:43.58 Window ManagerThe numbers on the right are the process ID's, which will be used in the renice command.
510 ?? Ss 0:01.47 loginwindow
516 ?? S 0:00.80 pbs
520 ?? S 0:06.32 Dock
521 ?? S 0:16.99 Desktop
522 ?? R 1:54.70 Classic
523 ?? R 4:48.62 TruBlueEnvironme
645 ?? S 1:25.55 Clock
658 ?? R 85:03.91 LaunchCFMApp
682 ?? S 0:27.84 CPU Monitor
683 ?? S 0:17.42 ProcessViewer
691 ?? R 0:02.86 Terminal
697 std Rs 0:00.16 tcsh
renice +15 522This will take my setting from the default, 0, to 15. The largest number is 20. The larger the number, the lower the priority. At 20, the classic environment will only get a chance to run whenever nothing else is going on. At 15 you will get a little sluggishness inside of your classic environmnt when it is bogged down, but you won't notice the impact anywhere near as much on the rest of the system.
renice +15 523
renice 0 522then you will have to be logged into your shell as superuser.
renice 0 523
