it’s pretty incredible how much time is spent in GC
Jeremy K.
David – memcaching recordings gave 28% speedup on the dash
Jeremy K.
probably bigger in production
Jeremy K.
I think GC between requests will be a pretty decent speedup too
Jeremy K.
but it’s harder to tell without deploying it
Jeremy K.
since the next request isn’t paying the penalty for all the trash the previous request generated

i’m seeing GC thrown around a lot here. What does it mean?
Jeremy K.
garbage collection
Jeremy K.
everything we do generates garbage :)
Jeremy K.
and Ruby has to clean it up

we generate SO much garbage that Ruby’s little mom-and-pop garbage company is strained to its limits
Jeremy K.
For some pages, we’re spending half of the request just doing cleanup
Jeremy K.
So decreasing the collections we have to do is a huge boost
Jason F.
No kidding. Glad we noticed that.
