svn commit: r1090784 - /subversion/trunk/subversion/libsvn_ra/ra_loader.c

New Revision: 1090784

URL: http://svn.apache.org/viewvc?rev=1090784&view=rev
Log:
Disable membuffer caching over ra_local. Even for svn blame,
the default settings don't lead to improved performance.
Clients like TSVN may still re-enable the caches if the same
RA session is being used for multiple consecutive operations.

  (svn_ra_initialize): disable membuffer cache
