performance issue with large number of files

From: Mark Weaver <mark_at_npsl.co.uk>

I've got a directory with about 12k files totally about 1gb that is
checked into svn. A svn ci in this folder is excruciatingly slow.
Partly this is size (~2gb of read, presumably diffing the files), but
mostly this is rewriting the entries file (about 3.2Mb written for each
file diffed => ~40gb of writes). Client version is reported as svn,
version 1.3.2 (r19776).

Is there anything that can be done to mitigate this? e.g. get client to
check on file modification time rather than diffing; and/or dealing with
"entries" in a more scalable fashion? I note it doesn't read the
entries file each time, is the write per file really needed?
