Re: [MIT-Scheme-devel] bookkeeping memory allocated per primitive

[Arthur A. Gleckler]

Rather than wait longer for any objections, I've just committed this
together with a change to the i386 and x86-64 back ends to improve
overall system performance by 20%, using the same unscientific tests.
(Do a two-stage build to get the effect.)

20%?!  That's a lot.  What do you attribute that to?  Is it the branch direction change, or the SYMBOL-NAME change, or something else?
