Walk with me on this quest to find the root and perhaps start thinking on the future of Ruby.

19. 50+ developers lo usan • EventMachine • DataMapper • Nokogiri • Gherkin (Cucumber) • SQLite3 ;-)
20. Aún asi...
24. Y peor aún...

48. “La culpa de que Ruby sea lento es de Windows”
49. ¿Realmente?
50. ¡A investigar!
51. Profiling 1.9.3 GCC y AQTime
52. Hot Spots (Hits)
53. file_expand_path → 131284 hits
54. file_expand_path call tree (….....)

58. file_expand_path → file_expand_path → file_expand_path → file_expand_path
59. Inception!
60. Inception!
61. file_expand_path_* (y amigos) → file.c
62. file.c
63. file.c • 5455 LOC • 99 #ifdef • 37 #if defined • 3 #if !defined
64. file_expand_path • 316 LOC • 15 comentarios • 13 #if* • POSIX + Windows + Cygwin • 1 goto • …
66. File.expand_path “” x 10_000
67. V:\ V:\a\b\c\d\e 0 0,05 0,1 0,15 0,2 0,25 0,3 0,35 0,4
68. WTF
69. File.expand_path “foo”, “bar” x 10_000
70. V:\ V:\a\b\c\d\e 0 0,1 0,2 0,3 0,4 0,5 0,6 0,7 0,8 0,9 1
71. WTF x2
72. 0 0,2 0,4 0,6 0,8 1 1,2 1,4 1,6
73. Ruby → C → POSIX-like → Win32 API
75. Fenix http://github.com/luislavena/fenix
76. Ruby → C → Win32 API
77. Specs!
78. Ruby no tiene tests para File.expand_path
79. Fenix::File.expand_path
80. 0 0,2 0,4 0,6 0,8 1 1,2 1,4 1,6
82. ¡Totalmente experimental! (no me hago responsable de nada)
83. patch load.c https://gist.github.com/1258289
84. SET RUBYOPT=-rfenix/replace
85. rails runner “0”
86. 1.9.3-p0 0 1 2 3 4 5 6 Ruby Fenix
87. Demo
88. 1.9.3-p0 0 1 2 3 4 5 6 Current Fenix Linux
89. Achtung! • Fenix es solo un experimento • Prueba de concepto
90. Usar nuevas Win32 API Windows XP+
91. Olvidarnos de Windows 95/98
92. Código más claro
93. Un Ruby más rápido es posible.
94. Ruby 2.0 • Plan para 2013 • 20 años
95. Tiempo de limpiar la casa
96. Y tirar todo lo viejo
98. Otros ejemplos
99. PHP 5.3
100. node.js libuv
101. libuv • Evented Library • Abstracción de OS • win/unix/bsd
102. Solo falta voluntad para lograrlo.
103. (y mejor actitud de la comunidad)
104. TheCodeShop http://thecodeshop.github.com
105. Importante
106. </rant>
107. Soy parte de Ruby-Core (asi que puedo quejarme)
108. ¿Preguntas? (yo tengo varias)
109. Recordar
110. Ruby != Rails
111. Ruby es mucho más que Rails
