I don't know.

It's something about impressing a bunch of guys from an MS shop that are looking to buy our software written using a bunch of Open Source technologies (PHP, MySQL, IRC, Perl, open standards such as C and then the non OS but still cool Delphi and Flash)

MS Shop Guy: Will MySQL be able to handle what SQL Server handled?

Us: Ever hear of SlashDot?

MS Shop Guy: Yes, why?

Us: That runs on MySQL and handles it fine.

MS Shop Guy: Oh, good, if there is a bottleneck, I want it to be in the hardware. We are looking at a server load of around 300-500 simultaneous users. Can MySQL handle that?"

Us: "Oh, of course, is that all? We tested this with 1,000 users on the 300Mhz machine in the back office there with less than 1% cpu usage"

MS Shop Guy: (Eyes in look of surprise and shock, and utter happiness) What about Latency?

Us: "Oh...", says one of the Russian programmers, "I had a friend test it out in Russia...and only had a latency of 100ms".

Oh... they walked out looking like they just left heaven.

And yeah, we are going to make that deal.
