I suppose if ra_svn takes 22s over the WAN, and ra_neon takes 38s on the
LAN... you might as well use ra_svn all the time on a single UK-based
repository. Obviously you don't get the other features of using
Apache-based repositories, but if you can live with that, then you're
good to go.
Can you serve repositories using svnserve and apache at the same time?
If so, do so, and tell people that large imports will be faster if they
change the protocol in the url. Most of the time (as you say people
don't do this very often) they'll happily import the files and go off to
lunch, or kick it off at hometime. I do this when retrieving files from
a remote VSS DB - it takes all night, but I don't care as long as it's
finished by the time I arrive next morning. Most people are used to some
tasks taking ages, especially network-related ones. We just work around
Commits for few files work very well over WAN links, I happily committed
a dozen files using a 3g dongle last week, so I think you'll be happy
with SVN in general from what you said in your mail.
Hyrum's progress report on httpv2 is looking exceptionally good, I
half-expected to see "we'll start this sometime", but it shows rows and
rows of "[DONE]". Hyrum's a star.
BTW. TortoiseSVN has a new repository graph, I don't know if that helps.
