Linux Benchmarks Makes No Sense

I created two computers with identical hardware, and run the benchmark programs in both starting at the same exact time.

What makes no sense is that the computer that has the lower average index (121) finished the race a good 30 minutes ahead of the computer wich showed the higher avg index (167). The only difference here were the operating systems, which I am not naming yet because it may have commercial implications, and frankly I need to understand the results before jumping to conclusions. Maybe lower index means better system? That would be absurd.

Anybody has any idea about what is happenning?

Test::Builder::Module(3)				User Contributed Perl Documentation				  Test::Builder::Module(3)

Test::Builder::Module - Base class for test modules SYNOPSIS
# Emulates Test::Simple package Your::Module; my $CLASS = __PACKAGE__; use base 'Test::Builder::Module'; @EXPORT = qw(ok); sub ok ($;$) { my $tb = $CLASS->builder; return $tb->ok(@_); } 1; DESCRIPTION
This is a superclass for Test::Builder-based modules. It provides a handful of common functionality and a method of getting at the underlying Test::Builder object. Importing Test::Builder::Module is a subclass of Exporter which means your module is also a subclass of Exporter. @EXPORT, @EXPORT_OK, etc... all act normally. A few methods are provided to do the "use Your::Module tests =" 23> part for you. import Test::Builder::Module provides an import() method which acts in the same basic way as Test::More's, setting the plan and controlling exporting of functions and variables. This allows your module to set the plan independent of Test::More. All arguments passed to import() are passed onto "Your::Module->builder->plan()" with the exception of "import =>[qw(things to import)]". use Your::Module import => [qw(this that)], tests => 23; says to import the functions this() and that() as well as set the plan to be 23 tests. import() also sets the exported_to() attribute of your builder to be the caller of the import() function. Additional behaviors can be added to your import() method by overriding import_extra(). import_extra Your::Module->import_extra(@import_args); import_extra() is called by import(). It provides an opportunity for you to add behaviors to your module based on its import list. Any extra arguments which shouldn't be passed on to plan() should be stripped off by this method. See Test::More for an example of its use. NOTE This mechanism is VERY ALPHA AND LIKELY TO CHANGE as it feels like a bit of an ugly hack in its current form. Builder Test::Builder::Module provides some methods of getting at the underlying Test::Builder object. builder my $builder = Your::Class->builder; This method returns the Test::Builder object associated with Your::Class. It is not a constructor so you can call it as often as you like. This is the preferred way to get the Test::Builder object. You should not get it via "Test::Builder->new" as was previously recommended. The object returned by builder() may change at runtime so you should call builder() inside each function rather than store it in a global. sub ok { my $builder = Your::Class->builder; return $builder->ok(@_); } perl v5.16.3 2011-02-23 Test::Builder::Module(3)
