I compiled and run the loop test code posted by Otheus.

Xeon/SCO results: 555555.56 semop/s [0,0]
Xeon/Linux results: 128205.13 semop/s [0,0]

I don't have access to PIII box right now, but as results are same (proportionally) as what I saw in my test I think it is not crucial not to have PIII results here.

As far as overhead mentioned by Era - I am aware of it, as it is closely resembles situation that I am evaluating, so it a valid test and not an oversight.

So, does anyone have any idea what the bottleneck could be? or where to look? I really appreciate your patience with me and your persistence in getting to the bottom of it.

App::Prove::State::Result(3pm)				 Perl Programmers Reference Guide			    App::Prove::State::Result(3pm)

NAME
App::Prove::State::Result - Individual test suite results. VERSION
Version 3.23 DESCRIPTION
The "prove" command supports a "--state" option that instructs it to store persistent state across runs. This module encapsulates the results for a single test suite run. SYNOPSIS
# Re-run failed tests $ prove --state=fail,save -rbv METHODS
Class Methods "new" my $result = App::Prove::State::Result->new({ generation => $generation, tests => \%tests, }); Returns a new "App::Prove::State::Result" instance. "state_version" Returns the current version of state storage. "test_class" Returns the name of the class used for tracking individual tests. This class should either subclass from "App::Prove::State::Result::Test" or provide an identical interface. "generation" Getter/setter for the "generation" of the test suite run. The first generation is 1 (one) and subsequent generations are 2, 3, etc. "last_run_time" Getter/setter for the time of the test suite run. "tests" Returns the tests for a given generation. This is a hashref or a hash, depending on context called. The keys to the hash are the individual test names and the value is a hashref with various interesting values. Each k/v pair might resemble something like this: 't/foo.t' => { elapsed => '0.0428488254547119', gen => '7', last_pass_time => '1219328376.07815', last_result => '0', last_run_time => '1219328376.07815', last_todo => '0', mtime => '1191708862', seq => '192', total_passes => '6', } "test" my $test = $result->test('t/customer/create.t'); Returns an individual "App::Prove::State::Result::Test" instance for the given test name (usually the filename). Will return a new "App::Prove::State::Result::Test" instance if the name is not found. "test_names" Returns an list of test names, sorted by run order. "remove" $result->remove($test_name); # remove the test my $test = $result->test($test_name); # fatal error Removes a given test from results. This is a no-op if the test name is not found. "num_tests" Returns the number of tests for a given test suite result. "raw" Returns a hashref of raw results, suitable for serialization by YAML. perl v5.16.2 2012-10-25 App::Prove::State::Result(3pm)
