Best Performance DataGrid for Winforms

I have an existing application in which i have to add/update around 5000 rows * 50 Columns at a time within One Minute.

On each row update i have to do following two things :

I have tested ComponentOne FlexGrid and DevExpress Grids so far. Both are good but when i send 100,000 orders, they keep jerking/freezing for few milliseconds.

Is there any best gridview exist inspite of that two grids ??
