Wei Deng commented on CASSANDRA-8150:
-------------------------------------
Can we also test increasing InitialCodeCacheSize and ReservedCodeCacheSize to
256MB? According to this JavaOne 2013 talk from a Twitter engineer
(https://oracleus.activeevents.com/2013/connect/fileDownload/session/DF4EE14FC64B279BC4C9E699C0231622/CON4540_Keenan-JavaOne2013-CON4540-Keenan.pdf,
page 47), the default settings are too low.

> It's been found that the old twitter recommendations of 100m per core up to
> 800m is harmful and should no longer be used.
> Instead the formula used should be 1/3 or 1/4 max heap with a max of 2G. 1/3
> or 1/4 is debatable and I'm open to suggestions. If I were to hazard a guess
> 1/3 is probably better for releases greater than 2.1.
