performance - Xcode suddenly becomes very slow

Question

My Xcode speed has come down to a crawl. I have no idea why. CPU activity is very low on both cores, gobs of memory.

It's almost as if it's waiting for something but I have no idea what. I have disconnected all USB and FireWire devices but it helped only a little bit.

Any ideas?

Answer 1

First thing I'd look at is the HDD. Is it constantly being accessed? If so, it would indicate several possible things - memory shortage and lots of swapping, hard drive free space shortage cause it to hunt for space, heavy fragementation etc.

If thats not it, perhaps Xcode is running something in the background. Do you have any custom scripts you have added which could have done something?

have you rebooted?
