check performance with Benchmark

Li Chen

Hi all,

I know I can use this format to check the performance
of my sctipt:

result= Benchmark.measure{##script included here##}

But this code will look ugly if the script spans many
lines.I wonder 1) if there is a better means and 2)
what if I want to check the same script for 10000
times.


Thanks,

Li

Hi,

1. you can put the script in a method/function and call that.
2. use 10000.times { } ;-)
either result = Benchmark.measure { 10000.times { script }}
or result = 1..10000.map { Benchmark.measure { script }}

Just look at the various pieces of sample code using benchmark that are
posted here (comp.lang.ruby / ruby-talk).

Kind regards
