Re: GDB using a lot of CPU time and writing a lot to disk on startup

This is what I get for the whole time that gdb is starting up:

Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util
sda 0.00 2073.47 0.00 1056.12 0.00 25036.73 0.00 12518.37 23.71 0.94 0.89 0.89 93.67
sdb 0.00 2073.47 0.00 1056.12 0.00 25036.73 0.00 12518.37 23.71 0.95 0.90 0.89 94.29

There are some reads from time to time but the writes are a constant.
Is there a way to determine the process that actually does the writing?

Thanks,
Nick
