[SunRay-Users] VPN Performance

[Ken Mandelberg]

We just started testing using Sunray 2's with the built in VPN support, 
running Easy VPN against a Cisco 5505. The performance level is 
disappointing. Even with the Sunray on the same 100mbit LAN with the 
Cisco's public port, I get utcapture numbers like

This is with just one active Sunray, doing some simple web browsing, no 
multimedia. Even a tiny multimedia window is really unusable.

Is this normal? If not where is the limitation? Is it the Sunray 
managing the tunnel, or the Cisco? Is there some tuning we are missing?

I had been using a Sunray 2 at home over cable modem, with a Solaris <> 
Solaris IPSEC tunnel provided by a workstation. That combo performs 
better over the internet, than the Sunray 2 does doing internal vpn 
against the Cisco directly on the lan.
