Thanks for the summary, Evgeny.
https://svn.apache.org/r1801974 adds negotiation and support for LZ4 in
mod_dav_svn and in ra_serf. Except for the PUT requests, [...]
It would be nice to see the same negotiation added for svnserve
protocol, if anyone is willing to do that.
Speaking of only using it with compression level 1, that's not a starting
point. While LZ4 offers superior speeds, it is not a substitute for any
zlib compression level > 1, including our current default of 5, as the
latter gives better compression ratio.
I was thinking that it might make sense to make the compression level 1 our
new default, so that new installations would benefit from the increased
speed, while still keeping a decent compression ratio. (If necessary, that
could still be tweaked for better compression.)
This feature would be a nice addition to 1.10.
Is 1.10 your target release? Given that it's on trunk already,
it would seem so :)
Is there any reason to wait before rolling a 1.10 alpha release?
danielsh made suggestions about the config option, in reply to the
commit email, which want opinions/follow-up, but need not necessarily
delay an alpha.
