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


version 0.60


These benchmarks were created by running

   etc/bench/ -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, 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.
