GP 10 takes too much time while posting Sales Transaction.

Dear All,

I am using Microsoft Dynamics GP 10. from last 3 days when I am going to post Single Sales Transaction Batch It takes 20 to 30 minutes. We are using AA and we don't have more then 2000 entry in Sales Order Process Module. 

Can any body tell me how can I resolve this issue.

Regards,
