Fast malloc for SMP machines?

[John Zedlewski <ze...@Princeton.EDU>]

Stop me if you've heard this a million times, but has anybody ever 
tried linking Apache with Hoard on a large SMP/ccNUMA machine?  It 
supposedly can dramatically increase the malloc speed of 
multi-threaded apps that simply link to it.  It's LGPL and uses C++ 
(although it works with C), so it wouldn't be standard distribution 
material, but I would be really interested to see if it helps the new 
multi-threaded Apache builds.  Unfortunately I don't (yet) have an SMP 
box on which to test it.  http://www.cs.utexas.edu/users/emery/hoard/

apache doesn't use malloc per se.  after an initial warmup period it
doesn't really need to touch malloc.  all allocations come from pools
which have no locking.  the benefit of hoard would probably be minimal...
