Strange. My test (quick copy paste from google):
```
1.9.3-p545 :002 > require 'benchmark'
 => true
1.9.3-p545 :003 > Benchmark.measure{ 10_000_000.times{ 'asdrsguoing93hafehbsefu3nr3wrbibaefiafb3uwfniw4ufnsbei'.include?('a') } }
 =>   3.990000   0.000000   3.990000 (  3.989146)

1.9.3-p545 :004 > Benchmark.measure{ 10_000_000.times{ 'asdrsguoing93hafehbsefu3nr3wrbibaefiafb3uwfniw4ufnsbei'.match(/a/) } }
 =>  10.520000   0.010000  10.530000 ( 10.552793)
```
