How can I speed up Subversion checkins? (Using ANKH, latest, Visual Studio 2010)

Question

I've started working on a new web project with some friends... we are using the latest Subversion server (installed last week), the latest version of ANKH.

My web project is a whapping 1.5 megabytes (that's with all images, css files, dll's after compiling, pdb files... etc).

Checking in even super small changes (literally adding the letter "x" to a few files for testing)... takes FOREVER! (about 10 seconds - I almost killed myself).

The ANKH client is measuring in BYTES PER SECOND ... BYTES? per second... I must be doing something wrong. Does anyone what config file has a joke totallyMessWithPeople=true so that I can turn that off or something?

Oh, also, changing one "big" file of a super 10k gains speed up to nearly the speed of light (which is apparently 857 bytes per second).

Help me obi wan kenobi, you're my only hope!

EDIT: As a note... my real work project that uses Visual Source Safe 2005 (I know, ouch) uploads files at about 200-500kbps from this very same computer/internet connection.

Answer 1

Note that when you use http:// or https:// the numbers AnkhSVN (and all other Subversion clients) show are not the real data transferred.

The neon library doesn't provide an actual bytecount, but just some indication on how far the contents is transferred, while some of the data is actually transfered in the headers. (The serf and svn layers provide better information). If you want to tell what the actual amount of data transfered is you need a separate tool.

When you just start a Subversion operation a lot of time is spend in opening a server session, especially on low latency links. (For AnkhSVN's development, I use a repository in California from the Netherlands). Subversion 1.7 will improve this handshake phase with it's new 'HTTPv2' handshake. (The v2 tells that Subversion uses different HTTP requests; it is still HTTP/1.1 on the line).

But there can be different reasons that subversion clients are slow (see the comments on your question): IPv4 vs IPv6 is a common reason, and a few releases ago the neon version used by AnkhSVN had a peformance regression on disconnecting from some https servers.

Answer 2

Earlier I said that I exported the cert and imported it as a "trusted root cert" and then my speed problems went away. That was true, but that's not the reason why my speed problems went away.

It turns out that I was just VPN'd into work, and so it was going slower. So, in my case, just disconnecting from my VPN increased my speed (obviously).

I just wanted to make this post so that people aren't lead astray by my earlier one.
