Subject: [ruby-core:60644] [ruby-trunk - Feature #9362] Minimize cache misshit to gain optimal speed

Issue #9362 has been updated by Eric Wong.


 Btw, have you time to investigate shrinking from 40 to 32 bytes?
 I'd be curious to see how 32 bytes works, not sure if it's doable
 without major API change/incompatibility, though.
