Re: Short term JSON eval cache (issue 10990076)

[dco...@codeaurora.org]

Reviewers: danno, Yang, ulan,

Message:
We mainly focused on seeing performance improvement on Sunspider and
ensuring
that other cases are at least neutral (no degradation) if there is no
noticeable
improvement. Unfortunately for some of these changes we were limited to only
evaluating performance for the benchmarks.

w.r.t. IdleNotification, we need to ensure cache entries are maintained
across
iterations of SunSpider in order for this to be useful. Maybe there's some
other
way to tweak how caches are aged? IdleNotifications trigger a major GC after
every test in SunSpider. What do you think?
