Performance improvement suggestion when comparing revisions of a large file

I work with a few large text files in SVN, say 50MB, and our server is not
on a LAN. When I use "SVN Show Log" on a large file and then "Compare
revisions" Tortoise downloads 2 full copies of the file, which takes 80
seconds The actual diff may take 5 seconds if not much changed. It would
be much quicker if it downloaded diffs instead. "Show changes" also
downloads 2 full copies of the file.

Compare my current revision and another revision, "Show changes" => just
download 1 diff from my current revision.
Compare a revision before my current and a revision after my current =>
download 2 diffs from current.
Compare 2 revisions both before / after my current => download a diff from
current to the nearer revision, then a diff between the revisions.
Compare 2 revisions with no current version => download 1 full file (the
earlier one?) and 1 diff.

Currently I work round this by keeping a local copy of every revision for a
few key files. It is really inefficient in disk space because there are
lots of small changes.
