Poor throughput performance with ASA-5505

I've seen a lot of people complain about this, but I haven't found any suggestions that work. Our Internet connection is 100 Mbps, but the ASA limits it to 30 Mbps. I've completely blown away the configuration and only put on the inside and outside IPs, bare minimum NAT configuration, and plugged one host into port 1 and confirmed both ends were 100 Mbps full duplex. I've disabled HTTP inspection, and I did confirm that the host plugged into the inside of the ASA actually gets the full bandwidth through speedtest.net. As soon as the ASA is plugged in, it dropped down to 30 Mbps. It was running 8.2(2) firmware, but I updated it to 8.2(5), and that didn't help. Any thoughts? Thanks

Cisco documentation says  throughput is upto 150Mbps , did you try enabling url-cache?

Thanks

Thanks for the reponse, but it didn't help out.

Were you able to resolve your problem? I have the same issue. Our internet speed is 100mbps but only getting 30mbps behind the 5505. I've read  to set the inside and outside interface to 100/full and not auto. Was wondering if you tried that.

Never did. We ended up getting a different firewall.
