Zoran, the boxes where you're tests show unexpectedly slow ns_malloc were all Mac PowerPC boxes running OS-X, is that right? If so, then the common thread here is OS-X, no? OS-X is known to be significantly less efficient than Linux in some areas, this is probably one of them?
Oh no... I had tested Linux and Solaris boxes as well. I have 2 Solaris boxes: one with 1 cpu and one with 2 cpu's. The same goes for Mac OSX. Unfortunaltey, I have only 1cpu linux boxes to test... What I saw is: 1cpu malloc better than ckalloc 2cpu ckalloc better than malloc regardless which OS. Cheers Zoran
