Faster Hash#slice (esp. when key count increases)
Reported by Cheah Chu Yeow | June 2nd, 2008 @ 09:46 AM
See title.
I claim no credit for this patch: credit goes to Grant Hollingworth (see http://merb.lighthouseapp.com/pr...). Just want to get it into Rails since it's trivial. I didn't replicate the Hash#except patch (until someone or I am able to profile memory usage).
Benchmark I used included. These are my results:
user system total real
small hash#slice_current 1.210000 0.000000 1.210000 ( 1.216810)
small hash#slice_patched 0.870000 0.000000 0.870000 ( 0.871604)
user system total real
big hash#slice_current 0.720000 0.000000 0.720000 ( 0.717137)
big hash#slice_patched 0.020000 0.000000 0.020000 ( 0.024483)
