"zero' and 'junk' options to help find and diagnose malloc abuse. EXTRA_SANITY defaults "junk" to on. Don't dump the internal state, unless EXTRA_SANITY. General code cleanup. Error messages cleaned up a bit, more checking earlier. EXTRA_SANITY is default at this time (just in case). Performance (without EXTRA_SANITY) is better, beats gnumalloc in both time & space most of the time: # In-memory test. ./malloc 50000000 2000 8192 159.2u 1.5s 2:41.85 99.3% 5+7742k 0+0io 0pf+0w ./gnumalloc 50000000 2000 8192 272.6u 0.4s 4:35.01 99.3% 5+8533k 0+0io 0pf+0w # Swap-space test. ./malloc 500000 14000 8192 6.5u 4.1s 4:08.87 4.3% 5+49209k 0+0io 9772pf+0w ./gnumalloc 500000 14000 8192 16.2u 14.5s 15:36.14 3.2% 5+54100k 0+0io 47651pf+0w # Small items test. ./malloc 20000000 20000 2048 67.0u 0.3s 1:07.83 99.2% 5+18199k 0+0io 4pf+0w ./gnumalloc 20000000 20000 2048 66.2u 0.3s 1:07.03 99.3% 5+18107k 0+0io 0pf+0w SANITY is not an option anymore.
