Hello,
Ive been using VMW for a while and i've noticed that exporting a full blu-ray as BD25 movie takes about 4-5 on CBR and double time on VBR
While using BD Rebuilder it takes only 1-2 hours on 2 passes.
What's wrong here? if you need any extra info just ask please.
Here is settings in both apps.
Thank you.

Probably BD Rebuilder is using faster encoding settings. You can look at the .ini file , or look at mediainfo on the output file. In your screenshot, VMW is using "Normal". If that correlates to the "medium" x264 preset, you can get 3-4x faster by using --preset superfast or ultrafast . Or you can make it 10-20x slower by using "placebo" .

Is there a quality vs performance issue here if i used fastest instead of normal?

I don't use WMW. I'm only guessing that the "performance" drop down correlates to the x264 settings. Because x264 is actually doing the "heavy lifting"
If it's too slow for you, try something faster, it's as simple as that. I think BD Rebuilder might be using --preset fast or faster on that run if it's about 2x faster -
One thing to keep in mind is that VMW adheres very tightly to BR specs. I have often found that a slow encode in VMW that works out of the box takes less time overall than a faster encode in other SW that needs to be redone. YMMV.
