RTSP higher delay in VLC 3

[vester]

We have been using VLC 2.2.8 for some time, and have gotten the delay down to around 230 ms when streaming, by setting the network-caching to 80.
This was an acceptable delay.

After updating to version 3+, that delay has really gotten worse.
After playing with:
network-caching=1
clock-jitter=0
clock-synchro=0
avcodec-fast
We can get it down to around 440 ms.
This is too much delay.

As we are using LibVLCSharp, we haven't tried version 4s --low-delay yet.

Do you have any suggestions what else i could look at to lower the delay?

I'd say, figure out what specifically caused the increase in 3.0 first.

Yes that would be nice. But I can only say that all 3+ versions I have tried have the problem.
I don't know how I should be able to say what new thing in 3 actually made it slower..
My guess is they come from different branches too, so finding a commit where it went wrong would be very time consuming
