I modified memtest to exclude thread related timings.
It is at the http://www.crystalballinc.com/vlad/tmp/memtest.c
when i call it with memtest 100000 and +, mallocs gettting faster than
Tcl alloc on my single CPU box

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.
