A performance tip

Before running svnadmin load or svnadmin recover, add set_flags
DB_TXN_NOSYNC in the DB_CONFIG file. It gives a massive speed
increase. Remember to remove it after since I'm not sure if it's safe.

Could svnadmin set the flag itself? It stupid for it to do millions of
fsync calls while running instead a handful when it completes. Try
running strace on svnserve, svnadmin or the apache. The number of fsync
calls made is truly staggering.
