Linux slows to a crawl when unarchiving a big file

archivinglinuxrarUbuntuubuntu-10.04

I started unarchiving a RAR file that this several gigabytes big. The computer is now going really slow, it's almost frozen. Sometimes I can move the mouse a little, but that's it. The unarchiving process seems to have halted, so now all I can do is restart the system. I don't think I can unarchive this file in Linux.

I never had this problem in Windows. How can this be fixed?

The slowdown is probably happening because of iowait. The ionice command should allow you to continue working:

ionice -c3 command
