svnsync experience

I'm in the process up setting up backups/read-only mirrors for
svn.plone.org using svnsync and so far my experience is somewhat
sub-optimal. I'm wondering if that is specific for my setup, or if
I am hitting some svnsync problems.

I need to replicate three repositories, totalling somewhat over 55k
changesets and about 1gb of data combined. There are two problems I
am seeing:

- svnsync appears have a memory leak. Looking at the process listing
  on every synced changeset it looses between a hunderd kB to over
  a megabyte of data. With 55k changesets needing to be processed that
  is somewhat problematic.

- svnsync is slow: it processes one changeset every 3-5 seconds. The
  latency between the machines is 160ms and neither of them are
  overloaded.

Combined this means it takes me about a week to setup one mirror (and I
need to setup two) for the repositories and requires me to manually
restart the svnsync process regularly to prevent the machine from
running out of memory. I'm really happy to have a tool like svnsync,
but currently it is slightly painful to use.

Are there things I can tweak or look into that can help?

Wichert.
