Cisco PIX 501 Throughput

Hi All,

Im looking for somewhere or someone that can give me accurate information about the throughput of a Cisco PIX 501. Cisco’s site lists these specs as 60mbps clear txt and 3-6mbps for vpn traffic, depending on encryption, what i need to know is: if i have 2 or more vpn tunnels running together, how is the total bandwidth of the unit affected, and what happens to the throughput of the cleartxt traffic running at the same time?

Really need to know for a network design decision, would appreciate any help or advice you can give.

Many Thanks in advance,

Adam Aquilina
