Bencher::Scenario::FileWriteRotate::Writing - Benchmark writing using File::Write::Rotate
This document describes version 0.002 of Bencher::Scenario::FileWriteRotate::Writing (from Perl distribution Bencher-Scenarios-FileWriteRotate), released on 2017-01-25.
To run benchmark with default option:
% bencher -m FileWriteRotate::Writing
To run module startup overhead benchmark:
% bencher --module-startup -m FileWriteRotate::Writing
For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
bencher --help
Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
Version numbers shown below are the versions used when running the sample benchmark.
File::Write::Rotate 0.31
fwr (perl_code)
Code template:
state $tempdir = File::Temp::tempdir(CLEANUP => 1); state $fwr = File::Write::Rotate->new(dir => $tempdir, prefix=>'fwr'); $fwr->write(<str>) for 1..1000;
fwr(lock_mode=none) (perl_code)
state $tempdir = File::Temp::tempdir(CLEANUP => 1); state $fwr = File::Write::Rotate->new(dir => $tempdir, prefix=>'fwr', lock_mode=>'none'); $fwr->write(<str>) for 1..1000;
fwr(lock_mode=exclusive) (perl_code)
state $tempdir = File::Temp::tempdir(CLEANUP => 1); state $fwr = File::Write::Rotate->new(dir => $tempdir, prefix=>'fwr', lock_mode=>'exclusive'); $fwr->write(<str>) for 1..1000;
fwr(rotate_probability=0.1) (perl_code)
state $tempdir = File::Temp::tempdir(CLEANUP => 1); state $fwr = File::Write::Rotate->new(dir => $tempdir, prefix=>'fwr', rotate_probability=>0.1); $fwr->write(<str>) for 1..1000;
normal (perl_code)
state $tempdir = File::Temp::tempdir(CLEANUP => 1); state $fh = do { open my $fh, ">", "$tempdir/nf"; $fh }; print { $fh } <str> for 1..1000;
