Re: MLM question (limits)
I knew I should not have said that because someone would ask
me to back it up and I cannot find the document. But in my notes from
an update from 9/97 I wrote that down. I also wrote down that the
reason had something to do with it being mulit-threaded on the NT.
It is not the same code as it is on Unix. When you get a chance to
do something over, sometimes you make it better! It is also true
that the Unix version has improved over the years.
I don't have access to the data, but I am comfortable telling you that
the two platforms have different performance characteristics re MLM.
And now I am going to shut up on this subject before I get in trouble.

Did I read that right
NT on a Pentium outperformed UNIX on a server
What size boxes. How can NT handle thousands and UNIX only hundreds - sounds
like something is wrong there
Where can I get that benchmark info
