I go to '
rm -rf foo,' realize that the directory foo is HUGE (50+GB), hit ctr-z, and try to background it in an effort to move on with my life.
Under 2.4, the process would suspend immediately, background immediately, and the interactive response was perfect (IMHO).
Under 2.6, I hit ctr-z, and nothing happens for up to 30 seconds.
Eventually the process suspends, and then I can background it, but it's totally unnerving. It makes me feel like I'm using Windows.
Is this a real change in 2.6, or am I doing something wrong? Did the scheduler change between 2.4 and 2.6?
nohupto run your jobs in the background, and you will be in good shape; it's really a better practice than job suspension anyhow.
