People keep bringing this up but I don't quite agree. Mac OS X has
"shark" which is pretty much what you describe above. However, having
used both, I prefer perf's simple UI for two reasons: it's much easier
to automate perf commands and text-based reports are superior for
sharing results (and keeping track of results when doing performance
That said, AFAICT, it should be pretty simple to implement a
shark-like UI with GTK as current perf code is pretty good fit for
that. I've pondered about doing that myself but quite frankly, I don't
see any big gains in that.
