Hi, I am using FreeBSD malloc from the current working branch. I hope its jemalloc. I tested it on a single CPU machine i could get the following results # ./malloc-test 1024 10000000 4 Starting test... Thread -1096811184 adjusted timing: 102.369100 seconds for 10000000 requests of 1024 bytes. Thread -1101005488 adjusted timing: 103.212512 seconds for 10000000 requests of 1024 bytes. Thread -1098908336 adjusted timing: 103.491399 seconds for 10000000 requests of 1024 bytes. Thread -1094714032 adjusted timing: 103.605124 seconds for 10000000 requests of 1024 bytes. I checked the result in the FreeBSD mailing list link given below: http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2005-12/msg00294.html The jemalloc gives very good results. Is that the performance is good only on SMP? Or on single processor also it should perform well? But on single CPU i could see bad results. Could anyone help me out? Thanks in Advance, Channa
