I did 3 kind of run after I was accustomed to most of the dungeon's mechanics:
  1. First run was solo. It was fine.
  2. Second run went in with pug. It was slower.
  3. Third run went in with my group of friends (one of them was first timer). We were melting things noticeably faster vs my own solo & the run with pugs.

I choose to just solo my way through the rest of my uncleared routes after my friends had to go lol.
