I have users complaining of poor performance for TCP applications over a site to site VPN.
I would like to know if anyone knows what to look for when trying to see if we need to reduce the MTU on each side of the VPN.
I dont want to reconfigure MTU unless I have to because one of the two sites is the centre of the hub and I will most likely have to configure it for all of the other sites if I configure it for the one.
the VPNs run between 5510 devices running 7.08 and 8.21
