The only thing that comes to mind about slow performance is the
insufficient entropy problem where Subversion's APR is set to use /
dev/random instead of /dev/urandom on a platform where /dev/random
can be slow. I don't know if your symptoms exactly match those
commonly observed by those experiencing this problem. You could try
recompiling your APR to link against /dev/urandom instead of /dev/
random. There may be another way to determine beforehand if this will
help (by doing some kind of trace to see what Subversion is waiting on).
