GCC vs ICC Compiler
Benchmarks - Perl
Executable Performance |
|
Following up on the interest shown in our Web Platform
Benchmarks, the engineers at UsenetBinaries.com decided to post the results of another
benchmark we did recently - which is the performance of the Intel ICC
Compiler for Linux vs GCC.
In order to download, reassemble, thumbnail, storyboard, pagegen and
database over 100k images and videos daily from the Usenet into browsable
and searchable web pages takes many CPU-days of Perl execution daily, in
addition to a great deal of C execution.
Since the Perl executable itself is a C program, the performance of
different resulting Perl executables from different compilers is of interest to anyone wishing to
speed up their Perl programs.
All of the tests were run standalone on an unloaded webserver consisting of
(1x) AMD Athlon(tm) 64 FX-53 Processor 2.4GHz (1024 KB cache) with 1GB RAM
running OpenSuse 10.2 (32-bit).
Previously icc had disabled some optimizations for non-Intel hardware, but
this restriction was lifted prior to version 9.1.
For the Perls we compiled by hand, the default Configure options were
selected except for destination directory and, of course, compiler used. The
-O3 option was defined to allow the compiler to decide its best-guess
optimization for executable performace.
The Benchmarking suite used was Perlbench 0.93 by Gisle Aas.
Perlbench reports its results by defining the first Perl selected as the
baseline at 100. The other results refer to the performance of the
exectuable *relative* to the first.
e.g. a score of '200' means that the result performed 100% better then the
baseline.
Obviously, higher scores are better
The Baseline Perl used is the default binary Perl package as distributed with
OpenSuse 10.2 (32-bit).
We need to put a disclaimer here as we did with the last benchmark - no,
this is not scientific and no, this is not the definitive benchmark for icc,
gcc, or Perl, its just one benchmark which may be of interest to many
people, so we're sharing it with the community - take it at face value.
