It's always interesting to get "third party" confirmations on such benchmarks so please post them :) > I knew about it and wanted to turn it off, but I was under the > impression it was enabled by malloc.conf, which was non-existent, > rather than at compile time.

Yes, they should be documented, and I've started something in that direction here: http://wiki.freebsd.org/DefaultDebuggingKnobs .
