For those of you running multi-socket Opteron servers (and eventually,
multi-socket Nehalem servers), AMD published a whitepaper last week on their
work adapting Google's tcmalloc to be NUMA-aware. The whitepaper includes
links to their source code / diffs. It appears to be quite a performance boost
in their (very artificial) benchmark. I'll be trying it out soon myself.
