Phillip Pearson: [PyCS-devel] pycs.net slowdown hopefully fixed

Hi all,

I think I cracked the pycs.net slowness issue -- the problem was not
actually to do with the PyCS code, but rather that mysql was taking a
really long time to process some topic exchange requests, and that was
holding up the whole machine.

Apache was spawning the max number of children, all of which were
waiting for mysql, and all the Apache and Python processes were using
all the machine's memory, so it started swapping, and made everything
even worse. Now I've added a key in the right place and mysql and the
topic exchange are zipping along happily, so with any luck everything
else should be OK too.

Tell me if you see any more serious slowdowns like this...

Cheers,
Phil
