Log:
Add compression, memory-cache-size and open-file-count
command line parameters to svnserve. The latter two are only
available (on the CL) if FSFS is supported.
Just wondering: are these features only relevant for svnserve, or
could they also be applicable (or a variation) to mod_dav_svn?
Those caches are active in FSFS per default although with
very conservative sizes, i.e.they are small. The caches are
much less effective in pre-fork servers (svnserve without
the -T parameter, Apache on most Unices).
If the
latter, do you plan to add a way to configure those options for
mod_dav_svn as well? Or are they available in some other way?
I plan to make these settings available for mod_dav_svn as
well. Windows servers should benefit the most from the new
caches. However, you would need 64 bit builds of Apache
and mod_dav_svn to handle large (1GB) caches.
It would be nice if mod_dav_svn users could enjoy the same performance
improvements as svnserve users (unless it's not possible for some
technical reason of course).
My idea is to provide a second caching level that is almost
identical to the current membuffer cache but uses a memory
mapped file to store the data. Thus, it can be shared among
multiple processes (e.g. pre-fork servers) and it allows for
moderate size (~16GB) caches under 32 bit.
