Hi Dragan,
Good to meet you in Kansas City.
When I do a MAX(PK) SQL statement with a network table of 250,000 records, it takes 9 seconds. That's quite a penalty for each time a user starts up.

>It is, simply because it's done low-level, somewhere in the table's header or so, so it's in a block which is already read, already has the locking mechanisms in place and generally does all the neat homework under the hood, and you don't have to worry about the stuff from the above paragraphs. While I may think that my newid() is nearly perfect (or let's say sufficiently perfect), I still know that that doesn't work perfectly in all of the situations. Native support is always better.

Said sufficiently perfect.
