Details

(Keywords: perf:pageload)

The GC will collect if memory usage passes a percentage of what it assumes is the working set, Either 150% during normal operation or up to 300% for "high allocation rate". If SpiderMonkey knows that page loading is happening (before first interaction) we could use the high threshold to attempt GCing at that time to get to the first interaction sooner.

Oh wait, that's not the same issue.

Paul, do you think this needs to be qf:p1. In general I haven't GC too often on pageloads (except those GCs after page load).

I haven't looked at pageload in a while, so I'm happy to go with p2. Thanks.
