Oops! I had thought I was using a Solaris machine, but it turns out I'm
using Linux. So, I've replaced the "sunos-x86.jar" file in my classpath
with "linux-i386.jar". Unfortunately, it does not seem to have solved my
performance problem.

I don't really understand the relationship between SVNKit and the
various jar-files. I suspect I'm including some superfluous jars - which
ones do I really need to speed up SVNKit? And which ones should I be
sure to leave out of my classpath? And do I need to make sure that I
have any particular C-libraries on my machine? If so, which ones, and
where can I obtain them?

The old, non-SVNKit version of my program and the new, SVNKit version
are running side by side on the same machine, and show the performance
difference.

I've made a JIP dump, but I was unable to send it to the mailing list,
probably because it's too large. I've sent you a copy of that dump
directly. Thanks very much for your help!
