SA540 Latency issue

I have a SA540 and the last 4 weeks or so, I've been having latency issue.  I do have a VPN connection with the office and pinging to a PC at the office is around 13ms.  I've turn off IPS, content filtering, protectlink, etc. and still get the same result.  The office has a 100Mbps Internet connection.  Thanks for the assistance.

Disable ContentFiltering under FIREWALL - 11ms

Enable ContentFiltering under FIREWALL - 205ms

Disable ContentFiltering under FIREWALL, Enable WebThreatProtection under PROTECTLINK - 212ms

Disable ContentFiltering under FIREWALL, Enable WebThreatProtection and URLFitering under PROTECTLINK - 226ms

The SA540 is underpowered, Cisco support recommends not Enabling any filtering if latency is an issue for your applications.

Without content filtering, the SA540 is like any other firewall in the market.  SAVE your money and buy a Netgear, Sonicwall, ZyXEL, Watchguard, etc.

HD,

You mentioned that you called into the support center; what was your case number? I would like to review your case to see if any things else could have been done. We can also lab your scenario up and test for performance issues.
