GWicke has uploaded a new change for review. https://gerrit.wikimedia.org/r/192762
Change subject: Increase the new generation to 1/2 heap ...................................................................... Increase the new generation to 1/2 heap Increasing the new generation to about 1/4 of the total heap combined with a higher tenuring threshold (number of collections survived before promotion) lets us catch more garbage in the young generation. This reduces the pressure on the old generation CMS collector, so that it does not need to fall back to slow stop-the-world GC as often / at all.
