The following reply was made to PR bin/5043; it has been noted by GNATS. From: Poul-Henning Kamp <phk@critter.freebsd.dk> To: Mika Nystrom <mika@cs.caltech.edu> Cc: freebsd-gnats-submit@freebsd.org Subject: Re: bin/5043 Date: Fri, 08 May 1998 21:42:06 +0200 >Ok, we now have a real application (it is a program that compiles >CMOS circuits into a simulator format) that exhibits really noticeable >slowness on free(). This is the output of kdump (I apologize for the >size of this file, but I am not the person developing the code in >question): Ok. got it and I have have looked at it, I can see that most of the memory goes into one 8Mb and one 256k chunk, but apart from that it looks pretty normal to me. I don't see any reason why the madvice() call should do much difference in the case you sent me the data for, it would only be called about 20 times or so in total... Was this a very simple case you ran ? If so, please run a "normal-sized" case, and just upload the gzip'ed ktrace.out file for me, don't waste your time running kdump on it. -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
