[Condor-users] Collector (multi-tier) or different machine

Does anyone have any insight as to how one might configure a pool where the collector is located on a different server than that of the central manager. I am asking because we have expanded our pool and our server (2 CPUs--3GHs) is running at 80% CPU load. Any jobs that we submit are taking as long as 10 hours before a match is found and the jobs run. The only thing I can think of is that the loading on the server is causing the problems, which has significantly increased after doubling the size of our pool.

Our pool includes all windows systems, we have approximately 115 slots and we are using the strictest of security settings (SSL, authentication, encryption, authorization, integrity).

I have read the wiki (https://condor-wiki.cs.wisc.edu/index.cgi/wiki?p=HowToConfigCollectors) about using milti-tier collectors, but for our system I think all I need to do is locate the collector on a different machine. I have set up the local configuration files so the COLLECTOR daemon is running on the second host, and the global config files specifies the host of the collector with COLLECTOR_HOST. The manual has no information on doing this, and I am not sure if the Collector daemon is required to run on the CM as well as the second host. After I made these changes, I can no longer query the machines in the pool.

Thank you for your suggestions,
