>If VFP is so strong in the middle tier then why does VB COM code run faster then VFP when in comes to transactions?

Where did you hear this, or where can I find out more information?

>Why would you ever consider using a language without multithreaded capabilities as THE middle tier platform ?

Because the need to spawn a thread rarely comes into play in a middle tier object. I have written my fair share of web apps and 3-tier apps that use the internet for communication with the server, and have never wished that I had a multi-threaded component on the server.
