Slow remote SVN. Fix?

I'm working with a very remote SVN that is pretty slow. My internet connection is good but the distance plays its part. It's not that slow, I can work. But it pisses me off when every diff 开发者_运维百科takes a second or two.

Is there a way to create a proxy SVN locally that constantly downloads the remote one?

Should I use local git or mercurial? They can bind to a SVN and can clone it.

I need something that doesn't need much effort.

You can create a local SVN mirror that stays in sync with the main repository, but create it as a write-through proxy, which means that when you try to commit the change actually gets forwarded to the master server then your server gets a copy of the change.

More info here: Mirror SVN Repository [Write-through proxying]

As far as I remember Subversion keeps the original (checked out/updated) file locally and performs the diffs locally. An svn diff does not involve network. A proxy would be difficult but you think to mirror the repository locally.

I don't think that a proxy SVN server has been done, since this would basically mean that a distributed version control system would have to be implemented, which is outside SVN's scope. git or mercurial are your best choices, since they support these features out of the box.
