VPN Latency Issues

I currently have a site to site VPN using two ISP's (Geographic separations) and I am seeing very large latency across when I run pings across it (300-500ms)  I understand the internet is best effort, but this is unusually high....on the network pings are returned 12-15ms...its just when they are initiated across the VPN that I see the high returns....I am running 3DES, and was wondering if going to 128 AES would alleviate the strain, or if I should check with the ISP's as well?

Hi,

isp if going to go off of ping speed, not vpn performance

try pinging with a full packet size, to see if you get the same amount of latency

try ping -s 65355 to the other site and vice versa

implementing another encrption protocol may help if ping return sizes are acceptable
