These benchmarks were created by running
.PP
.Vb 1
\&   etc/bench/bench.pl \-d . \-t 10 \-x
.Ve
.PP
for \s-1CHI 0.42,\s0 on \s-1OS X\s0 v10.6.6, 2.2 GHz Intel Core 2 Duo, Perl 5.12.2.
.PP
For each cache, \f(CW\*(C`bench.pl\*(C'\fR does repeated gets and sets of a data structure for
at least 10 seconds and measures the wallclock time per operation.
.PP
These numbers should just be used as a rough guideline! Actual results will
vary widely depending on system, get/set pattern, actual values being set, the
proper tuning of memcached/mysql, etc. For best results run the benchmark
script (available in this distribution) on your own system.
