FAQ.How to keep my web app from using 100% CPU time?

Answer: On Linux and MacOS you can use renice command in the terminal. On Windows use the task manager to reduce priority.

If you launch your app with nohup on Linux or Mac OS X like this from the terminal or a script:

nohup /webapps/MyApp/MyApp &

you can simply have a second line saying this:

renice 20 $!

which tells the system to lower priority to lowest value for the latest background process.
