[fedora-java] Oprofiling Eclipse CVS checkout

[Andrew Overholt]

Hi,

I'm trying to track down the cause of [1], so it was suggested to me that I
run oprofile and see what's going on.  I've done so and attached the
output.  I don't really know what I'm supposed to be seeing in this, so if
someone who knows more could help me out, I'd really appreciate it.

What I did:

1. sudo opcontrol --reset
2. sudo opcontrol --start --no-vmlinux
3. started eclipse and tried to check out GNU-Crypto [2]

   While this was going, I checked on gnu-crypto on the command line (on a
   different machine .. it's the same if I do it on the same machine as the
   one running Eclipse).  The command line checkout started when the
   Eclipse checkout was about 20% or 30% completed and finished before the
   Eclipse checkout made it to 40% (these percentages are just rough
   estimates based upon the progress bars).

4. stopped the Eclipse checkout while it was still less than 50% completed
   and cleanly exited Eclipse
5. sudo opcontrol --stop
6. sudo opreport image-exclude:/no-vmlinux

Thanks,

Andrew
