CGIAlt 0.0.1 released - an alternative library of 'cgi.rb'

Ruby
1

I have released CGIAlt 0.0.1.
http://rubyforge.org/projects/cgiext/

CGIAlt is an alternative library of ‘cgi.rb’.

  • Compatible with ‘cgi.rb’ and CGI class
  • Faster than ‘cgi.rb’
  • Available with CGIExt (which is an implementation of cgi.rb in C
    extension)

The following is an example of benchmark.

                                 cgi.rb      CGIAlt       CGIAlt

+CGIExt

require “cgi” (x1000) 13.16 7.89 ( 67%) 9.18
( 43%)
CGI#new (simple) (x100000) 20.34 14.53 ( 40%) 12.46
( 63%)
CGI#new (comple) (x100000) 26.62 20.10 ( 32%) 13.19
(102%)
CGI#header (simple) (x1000000) 12.68 6.05 (110%) 6.04
(110%)
CGI#header (complex) (x1000000) 43.52 36.26 ( 20%) 36.62
( 19%)

any thoughts on why i’m not seeing any speedup with this:

#! /opt/local/bin/ruby
require ‘rubygems’
require ‘cgi’
require ‘fcgi’
require ‘cgiext’

start_time = Time::now

memory_session = Hash::new{|h,k| h[k] = {}}

FCGI::each_cgi do |cgi|
this_time = Time::now

hack to get around ruby session bug

session = memory_session[[cgi.cookies
[‘_session_id’]].compact.flatten.first]
last_time = session[‘last_time’]
session[‘last_time’] = this_time

content = <<-html


START_TIME @ #{ start_time }

THIS_TIME @ #{ this_time }

LAST_TIME @ #{ last_time }

html

cgi.out { content }
end

??

cheers.

Hi ara, thank you for trying CGIAlt and CGIExt.

I have released new version of CGIAlt (0.0.2).
It now supports FastCGI.
Could you try new one?

sure.

can you confirm that, for cgi i should do

require ‘cgialt’
require ‘cgiext’

and, for fcgi

require ‘cgialt’
require ‘cgialt/fcgi’
require ‘cgiext’

and that, in both cases, i do not need to require either cgi.rb or
fcgi.{so,rb} ??

cheers.

CGIAlt and CGIExt are not the silver bullet for performance.
If CGI class and it’s methods were bottle neck of your application,
CGIAlt and CGIExt would be good solution.
But if not, you can’t find improvement of performance.

The following is an example of benchmarks. These benchmark scripts are
included in CGIAlt package and you can try them.

Table 1. summary of benchmark
cgi.rb CGIAlt CGIAlt
+CGIExt

require “cgi” (x1000) 13.16 7.89 ( 67%) 9.18
( 43%)
CGI#new (simple) (x100000) 20.34 14.53 ( 40%) 12.46
( 63%)
CGI#new (comple) (x100000) 26.62 20.10 ( 32%) 13.19
(102%)
CGI#header (simple) (x1000000) 12.68 6.05 (110%) 6.04
(110%)
CGI#header (complex) (x1000000) 43.52 36.26 ( 20%) 36.62
( 19%)

Table 2. result of bench.fcgi
Time taken for tests Request per
second

cgi + fcgi 16.686 [sec] 1198.61 [#/
sec]
cgialt + cgialt/fcgi 15.562 [sec] 1285.18 [#/
sec]
cgialt + cgialt/fcgi + cgiext 15.310 [sec] 1306.34 [#/
sec]

CGIExt replaces CGI.escapeHTML and ERB::Util.h and makes them much
faster.
If you use a lot of ‘<%=h var %>’, CGIExt will improve your
application’s performance.

this is what i’m testing:

START_TIME @ #{ start_time }

THIS_TIME @ #{ this_time }

LAST_TIME @ #{ last_time }

html

cgi.out { content }
end

and i don’t really see a huge improvement - but it’s a very simply
program that may not take advantage of the performance features. can
you suggest a fcgi that should see a significant speedup?
