Description:

Generate benchmarks to compare performance optimizations.

Makes use of the `benchmark-ips` gem as it provides a number of benefits like:
 - Simple significance test
 - Automatic warmup
 - No need to specify the number of iterations

Example:

`bin/rails generate benchmark opt_compare`

This will create:
    script/benchmarks/opt_compare.rb

You can run the generated benchmark file using:
    `bin/rails runner script/benchmarks/opt_compare.rb`

You can specify different reports:
    `bin/rails generate benchmark opt_compare patch1 patch2 patch3`
