ASA bandwidth limitation or...

Hope some one can point me to the right direction. Just procure a Metro-E Direct Internet Access (10MB), the provider actually is running ethernet over SONET. Anyway, they hand over a cat 5 into a router (Cisco2620), it's fastethernet port to my switch. Now, everything works fine if I plug in, for example, my laptop directly into the switch, I get over 9MB down and 7 ~ 8 MB upstream. If I plug into my ASA5520, and traffic flows thru this firewall, I am getting at max 3MB down and 1.5MB up. I am scratching my head. I need to dig out the ASA DOcumentation to see but I am quite sure the throughpout my ASA can handle should be a whole lot more than what I am seeing. Any idea?

Thanks for any help or pointers in advance.

hey Buddy..

I think speed problem is there...ASA5520 has Speed AUTO and Cisco 2620 has also - In most cases we seen this problem.

Can you make it hard cap of both devices wtih 100mbps/full duplex??

and observe he result??

DOne that, both interfaces are at full duplex 100MB. Still the same results.

What is the speed set on both the OUTSIDE, INSIDE & the respective connections to the Switch.

Set all of them to 100 MB & Full Duplex

Do you get any errors / CRC when you do a show interface ?
