Speed Up Combat

Tip number 1: If your game is too complicated to run from memory, it's too complicated. Bring loose notes and only refer to them when you forget something. Improve.

Tip number 2: Don't even roll initiative. He who takes initiative gets initiative. Then take turns in order around the table.

Tip number 3: Don't even use initiative. Strict adherence to the rules will slow the game down. The rules will slow your game down. Learn to make combat as freeform as your social interaction scenes.

Tip number 4: If you have players who aren't ready for their own turns, this might be a manners problem because it shows a lack of consideration for people's time. Politely let them know this and also notify them that in the future if they aren't ready on their turn, you'll skip their turn and rule that their character hesitated.

Tip 5: IRL timers for deliberation are good but tell your players there's a mean looking son of a gun with your shirt by the collar and his balled-up fist is holding a grimy battle ax and its coming for your face, and that strategizing is metagaming. Ask them what they do. If they let a beat skip and they don't tell you what they do, they get the bonks.
