LifeBoats that take that long to load, you might as well use a Emergency Transporter Unit and beam yourself to the shuttle bay, hop on board the Shuttle Craft, and GTFO.Lifeboats that take a long time to load to capacity are niche things if the intent is to be helpful when your ship is about to explode. Smaller is better when it comes to ejection. Just eject a few warp engines, too, and then propel the small pods to safety with those. The engines might otherwise be known as shuttlecraft...
The reason I decided to limit my DiTrigon shaped Escape Pod to 9x people is because loading 9x people is that right balance of "Alot of People" vs "Load People in Fast enough to GTFO".
