We finally determined what was causing very slow grid performance when AutoFitColumns is false.  Having a WebMenuBar object on the page causes this but no idea why this control would affect the grid in this way.

You can easily see the performance hit in the attached example.  All you have to do is load the page with the menu bar and then run it by removing the menu bar and you'll see a drastic performance increate when the menu bar is gone.

I had the grid set to load 30 of 830 rows and it loaded slower, menu bar on page, than 500 of 830 with the menu bar gone.

This is a critical issue for us so we need an immediate fix please.
