# CHI::Benchmarks(3pm)

Benchmarks of CHI and non-CHI drivers

## NAME

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

## VERSION

version 0.61

## 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.
