Your Mac Is Slow? Check CrashPlan Settings
To adjust Java memory usage, we can now use the CrashPlan app itself.
- Open the CrashPlan app
- Double-click the CrashPlan logo in the upper-right corner
- Enter the following command, using a value appropriate for the size of your backup selection (for example, 1536 for a 1.5 TB selection):
java mx 1536, restart - The CrashPlan app will close
The linked page also lists some recommended settings. You can check current memory (mx) settings with java mx. Much easier now, before we had to edit the launchd plist.
I have a MacBook Pro late 2013 at the moment, and I set it to 512, and my system feels much snappier now.
