I’ve ported Shugo M. excellent ruby-prof C extension to Windows.
ruby-prof is a code profiler like the built-in ruby profiler but is
orders of magnitude faster.
I’ve sent my patch to Shugo. In the meantime, I’ve posted a Windows
binary on my website for those who are interested. I’ve also written up
an article about the changes I had to make which were fairly extensive.
Hope people find this helpful,
