Filippo Giunchedi has submitted this change and it was merged. Change subject: Increase new generation size to 1/4 heap ......................................................................
Increase new generation size to 1/4 heap 1/4 heap is the Cassandra default, which we had deviated from during testing. We never got around to merging https://gerrit.wikimedia.org/r/#/c/192762/, so this resets things to defaults, with the hope that this might - decrease the number of ParNew runs, and - increase the amount of garbage that's collected in the new generation, and thus reduces the pressure on the old gen.
