Using Perl's Malloc

[zentara]

The post in Memory leaks and reference counting within Perl. jogged my memory about something I read in perldoc perlguts.

"It is suggested that you enable the version of malloc that is distributed with Perl. It keeps pools of various sizes of unallocated memory in order to satisfy allocation requests more quickly. However, on some platforms, it may cause spurious malloc or free errors."

So when I build Perl, it askes if I want to use Perl's malloc or the system's malloc, with it defaulting to system. Is there beter memory performance with Perl's malloc, and if so, what improvements could I expect on linux?
