At startup the command line client disables the new FSFS caching in subversion/svn/main.c:main (I recall that at one point FSFS cache initialisation was expensive but I believe that is no longer the case):
/* Per default, disable large expensive FS caching on the client side. * We can still chose a different size for that cache later in the * startup phase, e.g. after reading config files. If that does not * happen until the first FSFS repository get opened, low initialization * overhead caches will be used for the most time-critical structures. * * This is only relevant for FSFS over ra_local. */ settings = *svn_cache_config_get(); settings.cache_size = 0x0; svn_cache_config_set(&settings); but I don't see where we ever set it to a non-zero value or how we allow the user to control the cache size. Have we forgotten to do that bit? At the very least I think we should have a config setting. -- uberSVN: Apache Subversion Made Easy http://www.uberSVN.com
