He said cheaper and faster. It takes 5-10 minutes for IntelliJ to start up properly for me, and doing anything in it is just too slow. (rip)grep is way faster.
Yes yes, I need a better PC. (rip)grep would still be faster, however, but I would use the IDE.
Normally, the IDE is open at all times when you're coding. But if you don't code all the time, I can see how you may prefer to avoid IntelliJ and I would also do that if I was just searching for strings.
It sounds totally broken. IntelliJ starts in a few seconds for me. 10 minutes is crazy, maybe your system has no free RAM at all when you try that.
