GP VPN causing slowness

recently pushed out always-on vpn, but one site/office is reporting slowness when connected to it. The office is a managed office, so i have no control over their internal network.

 

When VPN is disabled they are able to hit 600mb download/upload. As soon as the user enables GP VPN, this cuts down to 20mbps. I have performed a packet capture on the client machine, and cannot see anything untoward - minimal ooo packets are retransmits.

 

Any thing i can check or change?

 

EDIT:

This is also happening for users in other locations, i just didnt spot it before as most of them have a slower internet connection. One colleague has 200mb fibre internet, when connected to GP VPN this drops down to 80mb

Re: GP VPN ausing slowness from one location only

Hello,

This could be a good candidate for a TAC case. I do know in the past there have been versions of GP that just didnt behave correctly and caused weird behavior. Perhaps see if there is a new client out there and read the release notes? Also what are the speeds of users that pass through the same PAN with and without being on GP?

Re: GP VPN causing slowness from one location only

ive amended the original post with further information as it is not just one office affected. Remote users also seem to be capped. A colleague tested it from home where he has a 200mb fibre connection, once globalprotect is up and running a speedtest shows this drop to 80mb.

 

We have raised a TAC case
