It looks like sinatra would benefit from some way to do Time.new better
[like maybe http://www.a-k-r.org/clockcount/index.html or hitimes somehow]

Rubygems could use a Dir.glob :just_directories => true method

merb could be run using thin–those IO#writes might be caused by mongrel [?]

all of them could use GC tweaking, so they spend less time there.

rails could use a faster logger [http://allgems.ruby-forum.com/gems?search=logger]

EM could use to call rb_clear_cache_by_class less [whatever causes that] and could use 1.9 for it’s faster VM.

Wow this is totally sweet..

there’s also a date perf library out there wonder how it differs from third base.

I’d love to see this run with one of the libraries that speeds up Time performance like third base.

[...] Profiling Ruby With Google’s Perftools from igvita.com Benchmarking, profiling and debugging are all areas where better tool support could really benefit the Ruby community. Built in benchmark library and extensions such as ruby-prof provide us with a minimal level of introspection to help identify the common bottlenecks, but they still fall short of the available tools for the JVM, or other dynamic runtimes.

@hgs: No callbacks. You can check the source even!

@nc: As far as I’m aware it won’t work with 1.9 out of the box. Albeit that’s a good feature request for Aman!

@cheapRoc: Great point. I have to admit that because I’m not a Mac user I tend to discount DTrace (since my forays into linux flavors of DTrace have all failed miserably). Definitely a great tool to keep in mind, especially if you have a Solaris box around.

Wow cool stuff.
There’s also a few benchmarks using gprof of 1.9 at
http://github.com/hogelog/ruby-1.9.1-p0/tree/ee0f53e2559af9b564176f000ec4cd35e01ec06a/sample/_gprof_out
if anybody would find them interesting. [looking forward to a 1.9 compat. release here]
