16MB may be "reasonable" for normal usage but it still has a significant
effect on the testsuite. The testsuite is an unusual access pattern, it
runs thousands of commands on small repositories. Using a 1MB cache I
can run the testsuite for ra_local/FSFS in 10m15s, with 16MB cache that
increases to 12m30s, a 20% increase. There is a similar increase when
testing ra_svn/FSFS using the default Linux svnserve (a threaded
svnserve has a shared cache so isn't affected).

svnserve and svnadmin both have a -M option, was there any discussion
about using a single letter option for this feature? This could be used
by the testuite to restrict the cache size, but for ra_local/FSFS
testing there is no way to restrict the svn client.

Should we add the -M option to the svn client?

Should we make it configurable via .subversion/config instead or as well?

If svnadmin gets configured by .subversion/config should we remove the
command line option?
