dprofpp B<-T> [B<-F>] [B<-g subroutine>] [profile]

|

|
dprofpp B<-p script> [B<-Q>] [other opts]
|
|
|
|
dprofpp B<-V> [profile]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The I<dprofpp> command interprets profile data produced by a profiler, such
|
|
as the Devel::DProf profiler. Dprofpp will read the file F<tmon.out> and
|
|
will display the 15 subroutines which are using the most time. By default
|
|
the times for each subroutine are given exclusive of the times of their
|
|
child subroutines.
|
|
|
|
To profile a Perl script run the perl interpreter with the B<-d> switch. So
|
|
to profile script F<test.pl> with Devel::DProf the following command should
|
|
be used.
|
|
|
|
$ perl5 -d:DProf test.pl
|
|
|
|
Then run dprofpp to analyze the profile. The output of dprofpp depends
|
|
on the flags to the program and the version of Perl you're using.
|
|
|
|
$ dprofpp -u
|
|
Total Elapsed Time = 1.67 Seconds
|
|
User Time = 0.61 Seconds
|
|
Exclusive Times
|
|
%Time Seconds #Calls sec/call Name
|
|
52.4 0.320 2 0.1600 main::foo
|
|
45.9 0.280 200 0.0014 main::bar
|
|
0.00 0.000 1 0.0000 DynaLoader::import
|
|
0.00 0.000 1 0.0000 main::baz
|
|
|
|
The dprofpp tool can also run the profiler before analyzing the profile
|
|
data. The above two commands can be executed with one dprofpp command.
|
|
|
|
$ dprofpp -u -p test.pl
|
|
|
|
Consult L<Devel::DProf/"PROFILE FORMAT"> for a description of the raw profile.

=head1 OUTPUT
|
|
|
|
Columns are:
|
|
|
|
=over 4
|
|
|
|
=item %Time
|
|
|
|
Percentage of time spent in this routine.
|
|
|
|
=item #Calls
|
|
|
|
Number of calls to this routine.
|
|
|
|
=item sec/call
|
|
|
|
Average number of seconds per call to this routine.
|
|
|
|
=item Name
|
|
|
|
Name of routine.
|
|
|
|
=item CumulS
|
|
|
|
Time (in seconds) spent in this routine and routines called from it.
|
|
|
|
=item ExclSec
|
|
|
|
Time (in seconds) spent in this routine (not including those called
|
|
from it).
|
|
|
|
=item Csec/c
|
|
|
|
Average time (in seconds) spent in each call of this routine
|
|
(including those called from it).
|
|
|
|
=back
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 5
|
|
|
|
=item B<-a>
|
|
|
|
Sort alphabetically by subroutine names.
|
|
|
|
=item B<-A>
|
|
|
|
Count timing for autoloaded subroutine as timing for C<*::AUTOLOAD>.
|
|
Otherwise the time to autoload it is counted as time of the subroutine
|
|
itself (there is no way to separate autoload time from run time).
|
|
|
|
This is going to be irrelevant with newer Perls. They will inform
|
|
C<Devel::DProf> I<when> the C<AUTOLOAD> switches to actual subroutine,
|
|
so a separate statistics for C<AUTOLOAD> will be collected no matter
|
|
whether this option is set.
|
|
|
|
=item B<-R>
|
|
|
|
Count anonymous subroutines defined in the same package separately.
|
|
|
|
=item B<-E>
|
|
|
|
(default) Display all subroutine times exclusive of child subroutine times.
|
|
|
|
=item B<-F>
|
|
|
|
Force the generation of fake exit timestamps if dprofpp reports that the
|
|
profile is garbled. This is only useful if dprofpp determines that the
|
|
profile is garbled due to missing exit timestamps. You're on your own if
|
|
you do this. Consult the BUGS section.
|
|
|
|
=item B<-I>
|
|
|
|
Display all subroutine times inclusive of child subroutine times.
|
|
|
|
=item B<-l>
|
|
|
|
Sort by number of calls to the subroutines. This may help identify
|
|
candidates for inlining.
|
|
|
|
=item B<-O cnt>
|
|
|
|
Show only I<cnt> subroutines. The default is 15.
|
|
|
|
=item B<-p script>
|
|
|
|
Tells dprofpp that it should profile the given script and then interpret its
|
|
profile data. See B<-Q>.
|
|
|
|
=item B<-Q>
|
|
|
|
Used with B<-p> to tell dprofpp to quit after profiling the script, without
|
|
interpreting the data.
|
|
|
|
=item B<-q>
|
|
|
|
Do not display column headers.
|
|
|
|
=item B<-r>
|
|
|
|
Display elapsed real times rather than user+system times.
|
|
|
|
=item B<-s>
|
|
|
|
Display system times rather than user+system times.
|
|
|
|
=item B<-T>
|
|
|
|
Display subroutine call tree to stdout. Subroutine statistics are
|
|
not displayed.
|
|
|
|
=item B<-t>
|
|
|
|
Display subroutine call tree to stdout. Subroutine statistics are not
|
|
displayed. When a function is called multiple consecutive times at the same
|
|
calling level then it is displayed once with a repeat count.
|
|
|
|
=item B<-S>
|
|
|
|
Display I<merged> subroutine call tree to stdout. Statistics is
|
|
displayed for each branch of the tree.
|
|
|
|
When a function is called multiple (I<not necessarily consecutive>)
|
|
times in the same branch then all these calls go into one branch of
|
|
the next level. A repeat count is output together with combined
|
|
inclusive, exclusive and kids time.
|
|
|
|
Branches are sorted w.r.t. inclusive time.
|
|
|
|
=item B<-U>
|
|
|
|
Do not sort. Display in the order found in the raw profile.
|
|
|
|
=item B<-u>
|
|
|
|
Display user times rather than user+system times.
|
|
|
|
=item B<-V>
|
|
|
|
Print dprofpp's version number and exit. If a raw profile is found then its
|
|
XS_VERSION variable will be displayed, too.
|
|
|
|
=item B<-v>
|
|
|
|
Sort by average time spent in subroutines during each call. This may help
|
|
identify candidates for inlining.
|
|
|
|
=item B<-z>
|
|
|
|
(default) Sort by amount of user+system time used. The first few lines
|
|
should show you which subroutines are using the most time.
|
|
|
|
=item B<-g> C<subroutine>
|
|
|
|
Ignore subroutines except C<subroutine> and whatever is called from it.
|
|
|
|
=back
|
|
|
|
=head1 ENVIRONMENT
|
|
|
|
The environment variable B<DPROFPP_OPTS> can be set to a string containing
|
|
options for dprofpp. You might use this if you prefer B<-I> over B<-E> or
|
|
if you want B<-F> on all the time.
|
|
|
|
This was added fairly lazily, so there are some undesirable side effects.
|
|
Options on the commandline should override options in DPROFPP_OPTS--but
|
|
don't count on that in this version.
|
|
|
|
=head1 BUGS
|
|
|
|
Applications which call _exit() or exec() from within a subroutine
|
|
will leave an incomplete profile. See the B<-F> option.
|
|
|
|
Any bugs in Devel::DProf, or any profiler generating the profile data, could
|
|
be visible here. See L<Devel::DProf/BUGS>.
|
|
|
|
Mail bug reports and feature requests to the perl5-porters mailing list at
|
|
F<E<lt>perl5-porters@perl.orgE<gt>>. Bug reports should include the
|
|
output of the B<-V> option.
