The first step is to find out what exactly is causing the load; whether
it's commits or updates or something else.

Subversion itself supports master/slave replication, where all commits
go to a single server but read operations can be served by many. Maybe
that's sufficient for your case, but it's hard to say without any
performance data. Sometimes just tuning the server configuration may be
enough.

Sure, you can split repositories amongst different servers. Or you can
use a commercial solution that provides master/master replication.
