I have a 10x10mb ethernet handoff connected directly to a pix 515(os 8.03 16m flash 128m dram). The performance is really bad on the download side, I'm talking 4.5 to 6mb of 10 on a consistent basis. I know it is the pix because when connected directly to the ethernet handoff with a laptop, the circuit runs 10x10 consistently. Here is another curiosity... The customer has another ethernet handoff from a cable provider that is 15x2, using the same interface on the same pix, I consistently hit within acceptable limits (90-100% of rated speed). I have matched the speed and duplex manually and the port is not reporting any errors, I even matched the mtu for the upstream router, nothing seems to change the performance. I know the pix is old and it will be an ASA 5510 if they can ever be purchased again. I wonder if there is any gotchas in this and the performance with the ASA will stink as well... Does anyone have any ideas/suggestions?
