>If it's inexepensive to increase the cache size, seems like something reasonable to try
absolutely, you just never let that thing drop below 80%.
My advice would be to also run C2 compilation at 100-1000 cycles (e.g. -XX:CompileThreshold=100) - it's a much slower startup (but they do have lots of CPUs), and it may not generate a good perf guided code but they will have a good idea how much code cache to dedicate.
