Re: Joel's Performance Issues WAS : Opteron vs Xeon

I would suggest that if multi-user functionality is needed, then
starting with single user tests is a similar waste of time.

There's good reason to look at it this way...

It is all too common for people to try to start building things with
primitive functionality, and then try to "evolve" the system into what
they need. It is possible for that to work, if the "base" covers
enough of the necessary functionality.

In practice, we have watched Windows evolve in such a fashion with
respect to multiuser support, and, in effect, it has never really
gotten it. Microsoft started by hacking something on top of MS-DOS,
and by the time enough applications had enough dependancies on the way
that worked, it has essentially become impossible for them to migrate
properly to a multiuser model since applications are normally designed
with the myopic "this is MY computer!" model of the world.

You may not need _total_ functionality in the beginning, but,
particularly for multiuser support, which has deep implications for
applications, it needs to be there In The Beginning.
