Live window... v e r y s l o w . .

When I try to connect to in the live window
CasparCG Live 1

It is very slow.
In the log I can se this:

[2020-10-28 23:53:38.754] [9808]  [info]    Sent more than 512 bytes to
[2020-10-28 23:53:46.994] [4404]  [info]    Received message from ADD 1 STREAM udp://<client_ip_address>:9250 -format mpegts -vcodec libx264 -crf 25 -tune zerolatency -preset ultrafast -vf scale=288:162\r\n

How can that be?

Seems to be a performance problem, What are your hardware specs?
