SSL/TLS VPN vs IPSec GlobalProtect: Odd

So my internet headend has the remote workers using GlobalProtect, and for some reason when I set it up years ago I never ticked the IPSec box for the tunnel.

Today I'm setting up another internet headend, and when I configured GlobalProtect I did tick the IPSec box.

I immediately noticed my connection was not laggy anymore. using Google maps as a benchmark when RDPd into a computer the SSL was laggy as hell, but on IPSec it was almost smooth.

Iperf shows the same speed, about 20mb for both connections, on UDP the jitter is less by a bit on IPSec.

So why am I seeing a huge rdp performance increase when using IPSec?
