Slow speed thru Site to Site VPN

I'm having slow performance thru a Site to Site VPN. I have an ASA 5520 in each site with the version 8.2(4) in both ASA's.

I have a 20Mb internet service in one side and in the other side I have 50Mb.

When I transfer a file from the Sita A to Site B I get a transfer rate of 130KB/S

Could someone give some guidance on this?

Slow speed thru Site to Site VPN

Hi Cesar,

Sometimes is useful to know if the slowliness if only with TCP applications.

Try to compare a PING response through the tunnel. You can even PING from the ASA itself ´´ping inside x.x.x.x´´ or from a PC.

There are some inspections or rules that can affect TCP.

If UDP or ICMP is also affected, then something else in the network could be going on.

I supposed is a good place to start, hope it helps ;-)
