[Swift-devel] CPU usage with provider-deef

[Mihael Hategan]

Yourkit (www.yourkit.com) has free licenses for open source projects for
their profiler. Point them to a globus web page that has your name, and
they'll send you the license. Alternatively, there are other profilers
out there, and I strongly recommend using them on such issues.
