Generally increasing the cache size is the most effective way to reduce
loads. Try increasing the cache to say 15000 (assuming you have enough
RAM on the server) and see how that affects the load rate. 2000 is a
relatively low setting, but that really depends on the size of the ZODB.
How many objects are in your ZODB? Are you using ZEO? (I assume not)
