Can it be issue with Purify, if it does not grow with zippy?
Also, while we are playing with optimization and tuning this month i have two things to add:
1. Having 2 identical configs notice the difference of virtual memory used in NS and AS just after start, looks like we consume a lot of memory
vlad 11100 0.0 0.6 37548 3264 ? Ssl 12:55 0:00 /usr/local/ns/bin/nsd
vlad 11136 1.0 0.5 13024 2712 ? Ssl 12:56 0:00 /usr/local/aolserver/bin/nsd
2.I was testing ADP speed between NS and AS and noticed that AS is faster and looking into code it is more flexible and optimized. I am going to backport adp stuff from AS to NS

Hi! I have found (yet still not fixed) a leak in the current code. It is not trivial to expose it, but it is there. How to reproduce? Build a Tcl lib with threads exabled, but before compilation, edirt the Makefile and replace -DUSE_THREAD_ALLOC with -DPURIFY=1 Now before running the server do: LD_PRELOAD=your_modified_tcl_lib.so When the server starts, log into control port and do: time {ns_thread join [ns_thread create "set a 1"]} 10000 and watch "top" utility how the process virtual and resident sizes grow and grow and grow... Now, stop the server, edit bin/init.tcl file and instead of foreach f [file channels] { if {![string match std* $f]} { close $f } } write if {0} { foreach f [file channels] { if {![string match std* $f]} { close $f } } } Start the server again and repeat the time {ns_thread join [ns_thread create "set a 1"]} 10000 The virtual and resident process sizes remain constant! It is important to recompile Tcl lib with -DPURIFY as this will disable the zippy allocator and fall-back to plain system malloc/free. This way the effect of the leak can be tracked by looking at the top output. I still do not understand why is this so. If somebody needs a nice puzzle-solving over the christmas, he's welcome!
