Memory usage Evan Phoenix - RubyConf 2007

• 1.8 garbage collector is simple, but too simple. • Rubinius uses modern techniques to decrease memory usage and increase throughput Evan Phoenix - RubyConf 2007

Fork you! Evan Phoenix - RubyConf 2007

In 1.8... • Start up a program. • Require all your code. • fork() the process. • Watch your memory double. Evan Phoenix - RubyConf 2007

In Rubinius... • Start up a program. • Require all your code. • fork() the process. • Watch (virtually) NO change in the memory footprint! Evan Phoenix - RubyConf 2007

Memory change per additional instance 1 2 3 4 1.8 rubinius Evan Phoenix - RubyConf 2007
