This in effect slows down the performance and ultimately the speed at which the checkout runs. Linux clients connecting to the same server do not cause this load on the server.

I'm not sure who to address for this issue as this not only happens with TortoiseSVN but with SlikSVN as well. Any direction would be appreciated.
Since this problem is not TSVN related but concerns the svn library code
and the interaction with SSH and multiple OS, suggest you ask these
kinds of questions on the Subversion users list:
http://subversion.apache.org/mailing-lists.html
you'll get better help there.
