Yes but he said it was previously only 50mb. That 250mb contains a lot of duplicated compiles: tiered compilation can generate not just two but up to I think 5 different compiles of the same methods! I think code cache management in Hotspot is not that great: eventually the server would probably converge on a bit higher than 50mb due to the more aggressive inlining, but 5x suggests the low value compiles aren't being properly discarded.
