IMHO fragmentation of the pool is loosing some of the power. So one central manager is better.
We have much smaller pool (about 200 CPUs) but very high load was caused due to a lot (more than 2K every hour) very small jobs (less than 1 minute each). After analyzing the jobs - we decided to build the jobs in a way that there will be less jobs (about 100 per hour) which last longer (about 20 minutes each) and the matching process is much faster now.
The central manager is PII-350 and for our cluster it is doing great job. It is always in Owner state (no jobs are assigned to it).
