[Swift-devel] hprof profiling of coaster services

[Mihael Hategan]

I'm looking for a complete trace (make sure you use cpu=times) in binary
format (format=b) that I can load and analyze in some profiler.

The think below says that waiting takes time. Which is not interesting
because at the same time waiting doesn't eat CPU.
