I''m implementing SVN running on Apache / Windows 2000 for my team.
I've noticed a great degree of slowness, although not enough to render
the system totally unusable. What's puzzling is that I'm not using
SSL.
I suspect the problem may be that Apache is using LDAP for Windows
Active Directory authentication of domain account names and passwords.
Any ideas?
