Long time user, first time poster.
We've used server version 1.6 with svnserve on an existing project and it works great. (All teams members are inside firewall)
We have a new project with outside collaborations and some not open source code, so we set up https:// Mod Dav using apache2 and pwauth for validation -- we have other resources and prefer using the same authentication for all for simplicity.
It "works" but the performance makes it nearly unusable. Monitoring the server using the top linux utility indicates many, many invocations of "pwauth" for a single client request. The next thing I was going to try was to install an sssd daemon on the server, but I wanted to ask if there was anything else I was missing.
Below are various version numbers / httpd config directives I think will be relevant. The host is actually a virtual machine hosted on a fairly high VMSphere server; the 1.6 svnserve subversion server that works well is on the same server so it seems unlikely that that would be the problem. (And other IPC mechanisms like secure copy (scp) show very good performance.)
CentOS release 6.7 (Final)
sudo httpd -version
DefineExternalAuth pwauth pipe /usr/bin/pwauth
# Require SSL connection for password protection.
