My workspace's CPU is always at 250%!

#1

Hello, I’ve just noticed my workspace’s CPU is being used 250% all the time.
I personally don’t see any slowness or anything, so I don’t care much, but I’d like to fix the problem as I am sure my workspace is on shared resources

I ran top, nothing interesting to say, the one that uses most CPU is apache, at around 5%

After several hours of high CPU usage, it dropped instantly to its normal levels, I don’t know what was causing it.
