Ruby contains a number of improvements in Release 1.9.3. Beside bugfixes and new features the Garbage Collector has been optimized.
The new interface to the module GC contains a number of methods, that are of interest for programmers, that are required to optimize long-running processes and to work with huge data amounts.
In Release 1.9.3 of Ruby the module GC has been extended with a method returning some statistics related to the garbage collector. The method is called 'GC.stat'. The following example contains an example how to use the new method.
1 2 3 4 5 6 7 8 |
# load modules require 'pp' # print outputs to stdout print "number of times the GC has been run: #{GC.count}\n" print "some statistics:\n" pp GC.stat |
When running the script you may get outputs like this:
number of time the GC has been run: 2 some statistics: {:count=>2, :heap_used=>43, :heap_length=>43, :heap_increment=>0, :heap_live_num=>7920, :heap_free_num=>9586, :heap_final_num=>72}
For details regarding the returned dataset, please refer to the online documention of the module GC.
