Retrieving and staging cpanelsync binaries bz2 - bzip2 vs pbzip2 ?

Hi was curious when installing Cpanel at the part where it goes through Retrieving and staging the /cpanelsync/* .bz2 compressed files, does Cpanel at all make use of pbzip2 [url=http://compression.ca/pbzip2/]Parallel BZIP2 (PBZIP2) if it's detected or does it just use bzip2 ? pbzip2 is one of the few multi-threaded compression tools which not only gives speed ups for multi-threaded compression, but also for decompression as well so potentially lead to faster cpanel installs ? PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 v1.0.2 or newer (ie: anything compressed with pbzip2 can be decompressed with bzip2). PBZIP2 should work on any system that has a pthreads compatible C++ compiler (such as gcc). It has been tested on: Linux, Windows (cygwin & MinGW), Solaris, Tru64/OSF1, HP-UX, OS/2, OSX, and Irix.

Hello :) I don't see any indication the installer utilizes pbzip2 (it's not installed as an RPM post-installation). You can open a feature request for this, or simple for the overall optimization of the cPanel installer at: Submit A Feature Request Thank you.
