infinitycjwatson: So, turns out that ftpmaster->cdimage rsync is a heck of a lot faster if one doesn't --compress. :P21:33
infinitycjwatson: Can you think of any reason to make that configurable in the cdimage source (ie: for imaginary people who run this codebase in places where the mirror isn't in the same rack?), or should I just delete it and be done with it?21:34
infinityI'm guessing that even for those imaginary users, you don't win much by trying to recompress an archive that's 99% comprised of compressed files.21:36
cjwatsoninfinity: I wouldn't have known that was there; just delete it, I think21:48
infinitycjwatson: Done, and committed PEP-8 cleanups for other people to make you happy. :P21:49
infinitycjwatson: I feel like an idjit for not noticing sooner.  I guess when you spend enough time building software, you forget how to run it.21:54
infinitycjwatson: You'd think one of the first steps in "why is rsync so slow?" would be to check CPU usage on the server.21:55
infinitycjwatson: Now, it's swapped from eating one of pepo's cores to being low CPU usage and in perpetual D state, so any further blame, I can throw at the SAN, which is more comforting.21:57
