Test failures for Test-Benchmark-0.004 on x86_64 architecture

Hi, Tests failed when I tried installing on 64 bit Ubuntu 12.04: PERL_DL_NONLAZY=1 /opt/perlbrew/perls/perl-5.14.2/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t t/test.t .. 13/36 # Failed test 'subtest '10 faster than 20 num' of '10 faster than 20' compare actual_ok' # at t/test.t line 60. # got: '0' # expected: '1' # Failed test 'subtest '10 faster than 20 num' of '10 faster than 20' compare diag' # at t/test.t line 60. # Got diag (141 bytes): # 'code1 was not faster than code 2' # ' 0 wallclock secs ( 0.00 usr + 0.00 sys = 0.00 CPU)' # ' 0 wallclock secs ( 0.00 usr + 0.00 sys = 0.00 CPU)' # Expected diag (0 bytes): # t/test.t .. 24/36 # Looks like you failed 2 tests of 36. t/test.t ..

It looks like modern systems are so fast the difference between calculating the factorial of 10 and the factorial of 20 even a thousand times still rounds the time it takes for both down to zero, so the test can't tell if the calculation of factorial 20 was actually slower. When I set the number of times to 10000 (on line 56 in t/test.t) it passes.

I, too, encountered this problem when attempting to install Test::Benchmark via 'cpanm' today. I am going to see if we can get this worked on at the upcoming New York City Perl Hackathon: https://github.com/nyperlmongers/nyperlhackathon2015/wiki/Test-Benchmark:--Adapt-tests-to-modern-architectures Thank you very much.

I had pretty much forgotten about this module. If anyone wants to take it over (this will be the first change in > 9 yrs!) let me know, F Show quoted text
