ASA 5505 slow internet access

[hugochengym]

Hi ALL expert

I replaced my old firewall PIX 501 by 5505 but it is very slow for internet access when using 5505. Do you have such experience for this case?

What configuration missing in my ASA 5505?

ASA Version: 8.4(3)

ASDM Version: 6.4(9)

Check your interface counters as its a common issue when you newly deploy  and connect your ASA with switch you dont configure or hard code the speed.

sh int e0/0

check for any CRC, duplex erros and other counters and also check on switch show logg and see any errors.
