Running on TeamCity 6.5.3 with an idle svn server and an idle build agent (on seperate machines). Most noticable in my environment on a clean checkout where the svn cli checkout of the repo takes 5mins, and the TeamCity agent-side checkout of the same repo takes 12+minutes.
For long running build agents this is not much of an issue. For cloud build agents with a few build configs with different vcs root settings (that include the big svn vcs root) it means the agent initially spends a lot of time checking out the same large svn repo. This is made worse by the poor performance of the svn agent-side checkout.
I did not find any issues on youtrack for slow agent-side svn checkout. Wondering if anyone else can confirm/deny the difference between svn cli and teamcity agent-side checkout performance in their environment.
