Export Clip from LumenRT

Hello everyone,

I'm wandering what is the normal time to export a video from LumenRT.

So I have a file (approximatly 2Go), and I use the preferences you see in the image below.

It took +30h for the video (3min 45s) to get exported, and I was wandering if this is normal?

Best regards,

PS : The specifications of the computer I'm using are below
