Contrary to what you might think worst pause time for V8 3.6.x and V8 3.7 - 3.15 should be roughly the same. V8 3.7 will also do 7 GCs in a row as a last resort. However in 3.6 if you hit a full collection it will always pause your app for much longer then a incremental collector of 3.7 and later would (given that everything is tweaked correctly). -- Vyacheslav Egorov On Mon, Nov 5, 2012 at 1:28 AM, Joran Dirk Greef <jo...@ronomon.com> wrote: > Recent GC changes in V8 are wreaking havoc with a production app. GC traces > are showing pauses of over 22 seconds.
