hitimes version 0.3.0 has been released. Now with windows support.

&nbsp;&nbsp;gem install hitimes

[http://copiousfreetime.rubyforge.org/hitimes/](http://copiousfreetime.rubyforge.org/hitimes/)

Hitimes is a fast, high resolution timer library for recording performance  
metrics. It uses the appropriate C method calls for each system to get the  
highest granularity time increments possible.

It currently supports any system with the POSIX call clock\_gettime(),  
Mac OS X and Windows.

Using Hitimes can be faster than using a series of Time.new calls, and  
it will have a much higher granularity. It is definitely faster than  
using Process.times.

{{ Release notes for Version 0.3.0 }}

\* switched to extconf for building extensions  
\* first release of windows binary gem  
\* reverted back to normal rdoc

Looks nice. I love how accurate it is over traditional Benchmark.

Wish list: 1.9 use, and also the ability to use the CPU clock counter  
[maybe guess or estimate the accuracy?]. That might be faster, for  
those of us that want speed over accuracy 🙂 [1] seems to use it, as an  
example. Anything to improve speed [like a C based measure, etc.]

Thanks much.

Thanks!

I'll get around to 1.9 at some point.

It looks like ruby-prof some assembler to get its timing calls. Unfortunately I  
don't know assembler, otherwise I may have gone that route.

I went with the lowest level timing API call I could find on each system. this  
means that on Windows it uses the QueryPerformanceCounter()[1] and  
QueryPerformanceFrequency() combination, on OS X is uses UpTime()[2], and  
everything else goes to clock\_gettime()[3].

Patches are always welcome :-). Feel free to contribute[4].

The Interval class is pure C. I may re-implement Timer in C, but not quite yet.  
In hitimes, the fastest way to measure the execution time of a piece of code is:

&nbsp;&nbsp;duration = Interval.measure { # your code here }

If ther are faster ways to measure the execution of code, I would happy to  
incorporate them.

enjoy,
