>Just curious. I reviewed an application (my competition) that was very similiar to my VFP application that was written in Clarion. The screens were incredibly fast with pretty much the same controls on the forms as my VFP app (tabs, push buttons, etc.) I have heard that VFP has intensive screen I/O and OOP contributes to performance issues. Can anyone shed some light on why there is this much of a speed difference between the two.

I believe that both historically and today, the distinguishing characteristic of Foxpro/VFP is the speed and robustness of the database engine. There are other app development platforms out there that have snappier GUI's than VFP's (Delphi, for one). There are certainly more powerful packages for developing numerically intensive applications. But none seems to aproach the capabilties of VFP's database engine.
