SAY WHAT ?
What real life personal experience makes you say that OSF/1 scalability is 'just awfull' ??

On SPECrate benchmarks DEC OSF/1 systems scale up approx. linearly up to 6 processors (which is the max nbr of processors for now, new announcements = biz.dec.announce, watch it).
Also the DEC 7750 (5 cpus) won the AIM (tm) hot iron award as the best AIM multi-user benchmark performer they had so far (5-cpu scaling > 85%, show me better scaling for AIM benchmarks)
A DEC 7760 will perform in excess of 1000 tps, using ONLY 6 cpus, more than 50% of the result your system achieves with 31 (!!!) cpus.

You might (or better as SGI DB Mktg Manager you should :-) read last weeks joint announcement between Oracle and Digital, announcing the largest in-memory database (8GB !) demonstration to achieve new levels of database performance. Of course run on a multi-processor, true 64-bit DEC OSF/1 system. (And really only possible there)

So in the future pls refrain from bashing other vendors, in my opinion it's bad style.
