I don't have Specweb specifically, but I know that Phil Ezolt did some work with
the Alpha lockmeter patches on 2.2 (Phil?). I'm currently trying to get time on
our Specweb testbed as it stands now, so I'll accelerate that request if
possible. I'm attaching a copy of the output from a lockstat trace of an AIM VII
(don't shoot - it's all I can find right now! ;) shared system benchmark at the
(I believe) 2000 user datapoint (4CPU EV67 ES40 w/ the max 2GB of memory).

I'll get lmbench numbers if they're more interesting to you; Oracle/SAP are a bit
tougher as there's no Oracle/SAP for AlphaLinux. As soon as one is available, I
can get results. Personally, I like the output of this one better than the
lockinfo in Tru64, but that's just me. :) HTH.
