NAME

       CHI::Benchmarks - Benchmarks of CHI and non-CHI drivers

VERSION

       version 0.54

DESCRIPTION

       These benchmarks were created by running

	  etc/bench/bench.pl -d . -t 10 -x

       for CHI 0.42, on OS X v10.6.6, 2.2 GHz Intel Core 2 Duo, Perl 5.12.2.

       For each cache, bench.pl does repeated gets and sets of a data structure for at least 10 seconds and measures the wallclock time per
       operation.

       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.
