I'm using svn.exe (1.9.5), connecting through svn+ssh using Plink. For a nearby DigitalOcean server (in New York, 60ms ping), I get checkouts and commits at hundreds of KB/s. But I am collaborating with someone from Australia and he was getting really slow checkouts and commits to the server.
After lots of troubleshooting, I couldn't find anything that would speed it up for him. I tried making a digital ocean server in Singapore to see if it would be fast for him, and still be fast for me. While it is faster for him, I ended up seeing the same exact poor speeds he was seeing. The Singapore test server has a 280ms ping for me. My checkouts go at almost exactly 60KB/s. However, if I checkout from a linux VM on my same machine, through the same internet, using the linux svn client, I get hundreds of KB/s even to Singapore. Worried it might be an issue with Plink/PuTTY, I tried copying a large file with PuTTY's pscp.exe, and it goes at around 3400 KB/s, without compression. Anyone have any ideas on what could be causing the slow down? A checkout of the same exact repository from the New York server goes around ten times faster. And a checkout from a linux VM on the same desktop I am running svn.exe from went about the same, even to the Singapore server. Everything also goes slow when I use TortoiseSVN and not the commandline. Let me know if there is any more information I can provide to help track this down. Thanks, Charles Alexander
