These are raw numbers, and inconsistent with each other.. I get fullGC
about 4x-8x slower than a incrGC on the same number of bytes.

 Can incrGC 300MB in 1600ms.
 Can fullGC 20MB in 400ms

We *know* that increasing these parameters makes macroBenchmarks go
faster. It also avoids methodCache and atCache flushes, which will slow
down computation. (This also makes it more feasible to have much larger
method&at caches.)
