A tool for roughly and quickly measuring your slow code. This is not intended to be a sophisticated tool, but rather a quick off the cuff way to measure which part of your code is slow.
It's profiling with print statements.
To use the tool first instantiate it:
ct = CodeTimer.new
Then insert named section markers throughout your code:
ct.start("Part1")
...
ct.start("Part2")
When you're done measuring:
ct.end
Which returns a formmated string containing the results:
Total Time: 17s
Part1: 11% / 2s
Part2: 29% / 5s
Part3: 47% / 8s
Part4: 11% / 2s
As seen above, the slowest portion of the code is between the Part3 and Part4 markers.
Why not use Benchmark?
I tried Benchmark first, but the block structure required too much rewriting of code due to scope issues (variable declarations etc). Also, I was more concerned with how fast the various sections are compared to each other, which CodeTimer does automatically.
- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
- Fork the project.
- Start a feature/bugfix branch.
- Commit and push until you are happy with your contribution.
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
