off via
malloc options than to comment out manually corresponding malloc.c

after each cvsup.
Unfortunately, run-time checks for the debugging features are
expensive, since the debugging code is scattered throughout
malloc.c. This pretty much mandates compile-time configuration, for
performance reasons.
I can disable statistics and debugging, if there's a general
consensus to do so. How much performance difference is the debug/
stats code making for you? I've only been disabling debug/stats for
benchmarking purposes, so I don't have a good feel for how much it
impacts overall system performance.
Thanks,
