DataGrid performance boosts for AllowPaging=false?

[DLLHell]

I have a Datagrid where AllowPaging=true is used as the default and AllowPaging=false can be used alternatively. 500 rows are usually the norm but can be reduced if necessary. For 500 rows, the grid with AllowPaging=true will display immediately, but the grid with AllowPaging=false will show a whited-out page during DataBind time for about 10-15 seconds before displaying when trying to show 500 rows. The fewer rows, the less time it takes but the white-out time is too prominent even with few rows. Putting it in a Div so it does not scroll past 1 page did not reduce the 10-15 seconds at all.

Are there any performance boosts I can try to get this to display faster, either in the ASP.NET code or in a Win2K server? I am pretty sure I did not see it take so long in another server before moving on to a different server so I'm hoping to solve this.

Thanks for any info or help.
