PSA5000 low performance with ssl vpn

[James1]

Hi
I ve around 700 users connected to a PSA5000 but we are not able to get more than 110 Mbs in throughout. We run tcp-mss 1360 on border router for ddos stuffs.

Anyone experienced the same issue?
Any experience or recommendation is appreciated.

Kind regards

Hi James,

Do you use SSL or ESP? 
with ESP you should have better performance. 

What if you enlarge the UDP4500 port for ESP traffic and check for max UDP Packets Per Second, might be an issue in that. 

Cheers!
