VPN connection speeds really slow?

directly coming off the cable modem, i am getting download speeds close to 30MB at a remote site. Once i connect via VPN, i get download speeds just below 1MB? I get 30MB from my desktop from the HQ ASA.

What could cause the poor speeds? This can't be normal. Speed tests ran via speakeasy.net/speedtest

Thanks,

Re: VPN connection speeds really slow?

Use the ping command to check the network or find whether the application server is reachable from your network. It can be a problem with the maximum segment size (MSS) for transient packets that traverse a router or PIX/ASA device, specifically TCP segments with the SYN bit set.

Refer to the below URL for more info:
