Re: Large Commit Issues! 10Mbps Upload cap on a Gigabit LAN

Thanks for getting back to me. But I've looked at every other possible
bottle neck. Anyother transfer from the server to client is blazing fast
(at least 450+Mbps). I had it down to just the PC & server talking, and
there is no way I could get a checkout done where more than 20Mbps bandwidth
use (I was checking the bandwidth usage as soon as I did a checkout or
checkin). I'm pretty sure it's subversion itself, doing some sort of memory
stuff, where a buffer size is set or something... Both my PC & Server are
running on Window (PC: XP SP2 Server: Win'03). It's just wierd! It takes
me a long time (>50mins) to do a ~5-10GB checkin/checkout. That's just
waaay too slow when I have nearly a TerraByte worth of data that I need to
put under version control. I read some other people were having similar
issues with checkin/checkout of large files, I mean 10-20Mbps is great, just
not so great on where you have a 1Gb connection with no bottlenecks. Once
again, thanks for any input on this matter. I am a passionate advocate for
open-source software, and if I would love to put show off a subversion
system to some of the microsoft groupie execs, so please help!

Regards,
Ahmed
