Determining Maximum Firewall Throughput

I am in the process of taking over the network responsibilities for the company I work for.  They currently have 2 Sonic Wall NSA 4500's setup with High Availability.   There is about 20 Site to Site VPN's with numerous client VPN's.

My boss would like to look into replacing these with Cisco devices (for his own reasons).  When comparing the specs on the Sonic Wall NSA 4500 to the Cisco comparable it would be around a ASA5540 - ASA5585-X.

Is there a easy way to confirm the current network throughput and find the most comparable Cisco device?

I would also need to make sure that my VPN throughput would be sufficient too.

Please let me know if you have any questions,

Thank you and have a great day,

Robert

How can I easily & effectively determine my current throughput so I can find the right device on the link you provided?

You could just look at the specs: http://www.sonicwall.com/us/products/NSA_4500.html#tab=specifications

Or do you want to measure throughput for a period of time to see what that looks like?

Correct.  I would like to measure for a period of time to see what it looks like.  I've already seen the specs, but wanted to compare actual throughputs with what the device can handle.

I was hoping there may be a software package for windows that I could run, or if you know of a better option.

I normally use PRTG for that: http://www.paessler.com/bandwidth_monitor
That should give you a good idea of what's going through.

Do you know of any other utilities that don't require extensive configuration?

The less configuration, the less exact the results of course.

But perhaps something on the sonicwall itself?
