Subject: [sup-talk] Tuning Ruby's GC params for faster `sup`

Hey everyone,

I'm sharing this to see if any else does this, and whether or not it makes
sense to include in the defaults.

`sup` was kind of slow for me, and sometimes took a few seconds to open up
an (albeit large) email thread. I ran `perftools.rb` on it to see what was
taking up so much time, and was surprised to find that ~ 60% of wallclock
time was spent in GC.

So, I tuned Ruby's GC to not run so often, resulting in GC now taking only
13% of wall clock time. Anecdotally, I also noticed that threads loaded
much much faster. The params I set were
https://gist.github.com/rvnd/756d6a5e82d1bba9fbb9.

Anyone else notice this? Are there any other tricks people use to speed up
`sup`?

Regards,
Aravind
