Update: For the example script, there is no noticeable difference when comparing Perl v5.20+ against cperl v5.22+. I had compared Perl installed on the OS; Perl 5.18.2 (Mac OS X 10.11.6) and Perl 5.16.3 (CentOS 7.2) against cperl 5.22c. Thank you dave_the_m for catching this.

Thank you for cperl, rurban. I entered a demonstration running 25% to 33% faster with cperl depending on the platform.

Re^3: use threads for dir tree walking really hurts

Furthermore, the optional modules for MCE and MCE::Shared work without a glitch. Unless PDL is present, MCE and MCE::Shared will use Sereal 3.008 or later for serialization if available on the system. Storable is used otherwise. The IO::FDPass module is beneficial for passing file descriptors to the shared manager process. This applies to MCE::Shared::Condvar, MCE::Shared::Handle, and MCE::Shared::Queue.

1. Canary-Stability-2011 (required by IO::FDPass)
2. IO-FDPass-1.1 (optional, used automatically by MCE::Shared)
3. Sereal-Decoder-3.015 (optional, used by MCE and MCE::Shared)
4. Sereal-Encoder-3.015 (optional, ditto)
5. Sereal-3.015 (optional, ditto)
6. MCE-1.805
7. MCE-Shared-1.804 (add-on module for MCE)

The modules listed above work flawlessly with perl11/cperl Github branches maint-5.22c and maint-5.24c. Threads is not required to run MCE or MCE::Shared. I built cperl with threads support and that works too.

./Configure -Dprefix=/opt/cperl-5.22c -sder -Dusethreads -Dusecperl -A
+ccflags=-msse4.2

./Configure -Dprefix=/opt/cperl-5.24c -sder -Dusethreads -Dusecperl -A
+ccflags=-msse4.2

Thank you for making Perl run faster.

Warm regards, Mario.
