# A basic, synthetic benchmark of the impact HTTP client has
# on the speed of talking to ElasticSearch in the Tire gem.
#
# In general, Curb seems to be more then two times faster the RestClient, in some cases it's three
# to five times faster. I wonder if keep-alive has anything to do with it, but it probably does.

Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

# patch OAuth class to be able to create multipart requests (required for image uploading)
# NOTE that for my purpose I simply made it "auto-sensing" that an image is passed and
# only then creates a multipart body. You may simply want to use some flag instead or whatever.

Changes:

• this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

  ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

• this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

  This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.
