PIX/ASA NAT Performance issue

Hi experts,

Do anyone know that how nat affect the performance (speed)? As I found that the response is slower when I am setting nat at the PIX/ASA. Here is my situration:

Server <=> PIX <=> Client

Testing with a tcp streaming server:

1. Without setting NAT for the client, we can neg. with the server in client successfully within 20 seconds

2. With setting NAT for the client, the result is much slower, it seems we need to wait around 2-3 minutes for the streaming neg. and play the video

Please help.
