We have a point-of-sale system that was developed using ado.net, our current concern is to make the application real fast in creating transactions (sales). Usually there are no performance concerns with high end PCs but with with low end PCs, the transactions take really slow.
The main concern is on saving transactions which usually calls a lot of stored procedures for inserting records within a single transaction. This usually takes time on low end PCs. We need to improve the performance since most clients will only use low end PCs to act as cashier machines. One solution we are thinking is to use entity framework for data access. The entire project is written using ado.net and development time if we shift to entity framework would be alot. Any suggestions?
