Times I got on E1M1 (Ultimate DOOM)

demos.rar

Source Port used: Crispy Doom
WAD used: Ultimate DOOM (obviously)

To play the demo, add "-playdemo (demoname)" to the launch prompt on your batch file.
Or just drag the .lmp file over the .exe file.

 

For some reason by 7zip can't open the rar-file. It would be nice to have some information about the times you got in the post. Not sure if it is worth a thread, unless you actually got 8 seconds, but I think you would have stated that one. Dragging an lmp file over THE exe only opens Crispy Doom, but I guess you were talking about prboom+/glboom+, which was not stated in the post.

There is a thread for udoom videos. Time is around 11 sec, for those who are interested.
