We have a Pix 525 at our HQ that sits behind our Internet router which terminates our ISP connections. We are having throughput issues. Our connection is supposed to be 8 MB by 8 MB but we are getting 8 MB on the upload but only 1-2 MB on the download side. I have tested in front of the Pix 525 and throughput is around 6-7 MB. Behind the Pix 525 and it is much slower. The CPU utilization is around 20%. The ping tests do not show the latency. Are there commands on the Pix where I can further isolate the issue? I am running version 7.0(6). Thanks.
