Hi;

JIC you are not following freebsd-hackers, there was an interesting
discussion about the linux thread-aware malloc that is under a BSD
license. This link comes from an older thread:
http://docs.freebsd.org/cgi/mid.cgi?420BB1FF.11156.68F6CEC

It does look interesting (at least for SMP), but it looks like some
kernel support will be required.
cheers,

    Pedro.




I think Greg Lehey recently did some benchmarks that showed PHK malloc
greatly out performs ptmalloc.
phkmalloc is slow when allocating large space, I ever tried to allocate
512M in a single malloc() call on AMD64, and it cames up to several
seconds to complete the request.
