Peter Schuller commented on CASSANDRA-1968:
-------------------------------------------
Anyone got a good feel for how much pause times will be affected after
long-time use? WIth a fixed new size, I'm a bit paranoid about pause times
creeping up as young gen becomes more fragmented etc. However I'm not up enough
on how CMS old-gen is managed to know whether this is an expected result.
