I am having slow application performance thru a site to site VPN. I am running MS SQL and Oracle database applications thru the tunnel.
I have a 10 MB pipe from the ISP on both ends of the pipe. These are different ISPs. I have done speed tests and I am getting 10 MB up and down, just what we're paying for.
I have an ASA 5505 running the latest 8.x version on one side. This is 10 MB via fiber provided by Charter.
I have an ASA 5540 running version 7.2 on the other side.
There's a site to site VPN between the 2 locations using 3DES-SHA. I even tried 3DES-MD5 and DES-SHA but that didn't make any difference.
I looked at how much of the bandwidth I'm using and it's only using 3 MB of the 10 MB pipe. I am getting a ping response of 55 ms (average) during the day and 45 ms (average) after hours.
I tried a ftp transfer thru the site to site VPN tunnel and I'm getting pretty close to 10 MB.
I looked to see if I'm dropping any packets and it looks clean (no drops). I also checked with the ISPs and they're not seeing any dropped traffic either.
I'm also pushing VOIP traffic thru the VPN tunnel without a problem.
I have a case opened with Cisco but so far we haven't gotten anywhere.
Anybody have any ideas on how to improve the application performance?
