https slow

Hi I am having some slow downs accessing svn through https:

I am using subversion 1.4.2 on window 2003 server R2. Is this by any
chance a know issue?

Is there anything you can recommend to optimize performance?

Additional info about the build

Apache/2.0.59 (Win32) DAV/2 mod_ssl/2.0.59 OpenSSL/0.9.8d
mod_auth_sspi/1.0.4 SVN/1.4.2 PHP/5.2.0
