So, in my first real test of svn, I set up a server (using dav over https)
for some friends doing the ICFP programming contest (they've done 219
revisions so far in two days, the repository, without archiving the logs,
is 52mb). This is Debian Linux running 2.4.21 on an Alpha, if it
matters. The svn server components are built from r6305, apache is
2.0.46. Anyway, everything has worked pretty well (it seems a bit slow,
but that's another question), but I'm bit confused by the memory usage of
httpd. There is no web traffic on this server except for svn. I've
included a "top" output below from just now, and as you can see, it's 2
days of use. The httpd's (using prefork mpm) have grown from about 4mb to
14-22mb over the weekend. There's no swapping so far, but the free memory
has dwindled to 20mb from 400mb at reboot and startup.
My question is, is this normal? Should the httpds be constant size, or do
they grow like this to fill physical ram, or is there a memory leak, etc.?
Also, generally, what's the right way to look at the performance/memusage
of svn? top is pretty coarse grained...I've also tried atsar without much
luck.
Thanks,
Chris
