RSI is a simple full text search engine implementation in Ruby. It aims to be easily useful within other programs: simple to set up, simple to use. An emphasis has been placed on getting functionality out the door, rather than heavy optimization (that can come later). It still appears to be reasonably fast and efficient (while admitting to have not been heavily profiled...).

ruby-prof is a fast code profiler for Ruby. It is a C extension and
therefore is many times faster than the standard Ruby profiler. It
supports both flat and graph profiles. For each method, graph profiles
show how long the method ran, which methods called it and which
methods it called. RubyProf generate both text and html and can output
it to standard out or to a file.

Color is a Ruby library to provide basic RGB, CMYK, HSL, and other colourspace
manipulation support to applications that require it. It also provides 152
named RGB colours (184 with spelling variations) that are commonly supported in
HTML, SVG, and X11 applications. A technique for generating monochromatic
contrasting palettes is also included.
The Color library performs purely mathematical manipulation of the colours
based on colour theory without reference to colour profiles (such as sRGB or
Adobe RGB). For most purposes, when working with RGB and HSL colour spaces,
this won't matter. Absolute colour spaces (like CIE L*a*b* and XYZ) and cannot
be reliably converted to relative colour spaces (like RGB) without colour
profiles.
Color 1.8 adds an alpha parameter to all <tt>#css_rgba</tt> calls, fixes a bug
exposed by new constant lookup semantics in Ruby 2, and ensures that
<tt>Color.equivalent?</tt> can only be called on Color instances.
Barring bugs introduced in this release, this (really) is the last version of
color that supports Ruby 1.8, so make sure that your gem specification is set
properly (to <tt>~> 1.8</tt>) if that matters for your application. This
version will no longer be supported one year after the release of color 2.0.

The capabilities of the Color library are limited to pure mathematical manipulation of the colours based on colour theory without reference to colour profiles (such as sRGB or Adobe RGB). For most purposes, when working with the RGB and HSL colours, this won't matter. However, some colour models (like CIE L*a*b*) are not supported because Color does not yet support colour profiles, giving no meaningful way to convert colours in absolute colour spaces (like L*a*b*, XYZ) to non-absolute colour spaces (like RGB).

zenprofiler helps answer WHAT is being called the most. spy_on helps
answer WHERE those calls are being made. ZenProfiler provides a faster
version of the standard library ruby profiler. It is otherwise pretty
much the same as before. spy_on provides a clean way to redefine a
bottleneck method so you can account for and aggregate all the calls
to it.
% ruby -Ilib bin/zenprofile misc/factorial.rb 50000
Total time = 3.056884
Total time = 2.390000
total self self total
% time seconds seconds calls ms/call ms/call name
50.70 1.64 1.64 50000 0.03 0.05 Integer#downto
19.63 2.27 0.63 200000 0.00 0.00 Fixnum#*
14.19 2.73 0.46 50000 0.01 0.05 Factorial#factorial

5.54 3.23 0.18 2 89.40 178.79 ZenProfiler#start_hook
Once you know that Integer#downto takes 50% of the entire run, you
can use spy_on to find it. (See misc/factorial.rb for the actual code):
% SPY=1 ruby -Ilib misc/factorial.rb 50000
Spying on Integer#downto
Integer.downto
50000: total
50000: ./misc/factorial.rb:6:in `factorial' via
./misc/factorial.rb:6:in `factorial'
