Benchmarking with RVM
If you have a bit of code that you would like to benchmark across several versions of ruby all at once you can now do this easily with RVM. Given:
$ cat increment.rb
require 'benchmark'
puts RUBY_DESCRIPTION
puts Benchmark.measure do
y=0
1000.times do |x|
y = x + 1
end
end
We can benchmark this code against multiple ruby versions very easily:
