[I assume this was meant to go to the list as well, so I'm adding it
back to the CCs]

It occurs to me that tweaking the GC parameters can probably make a big difference: is starting with a bigger heap likely to help, or more generations? My generation hypothesis is that more generations will encourage the cached data to drop down out of generation 0, reducing the GC load.
Starting with a bigger heap is likely to help, since it means that GCs will be needed less often. I'm not sure I buy your generation hypothesis, because even with two generations, you would expect to see some of the cached data move to generation 1. Lots of data in generation 0 implies your code continues to allocate many objects as it goes on running. On the other hand, you could still try and see if it helps.
