IPSec Tunnel performance tips?

L4 Transporter

Hello folks,

 

I've seen a this article about improving performance by enabling this Adjust TCP MSS.  Ours is not enabled.

https://live.paloaltonetworks.com/t5/Management-Articles/How-to-Improve-Performance-for-IPSec-Traffi...

 

Would this be enabled on the public internet facing interface?

I do see some TCP retransmission and reassembled messages in the pcap. 

 

Our IPSec peer is complaining the application they are using from our side is very slow running and downloading Oracle Apex reports.  Blaming the network and IPSec tunnel since the reports run much faster from Starbucks WiFi.

 

Wondering if anyone may have a suggestion or comment?

Hello,

While I could be wrog, I think the change should be made on the layer 3 interface you have your portal/gateway config connected to.
