--- Comment #16 from Chip Salzenberg <chip at pobox dot com> 2012-07-26 22:50:17 UTC --- In my tests, with this patch, 4.7.1 is about 10% slower than 4.6 ... a vast improvement but certainly not parity. ./bench46 1.75s user 0.82s system 99% cpu 2.577 total ./bench47 8.01s user 2.78s system 99% cpu 10.800 total ./bench47+patch 1.95s user 0.80s system 99% cpu 2.764 total
