During testing with 0 ms delay and with a level 47 healer (which is bad if you didn't know already)
I averaged 6 turn-ins every minute aka 37,500/min, 2,250,000/hour.
This increases based on your character's ability to one shot the boar & available gold boosts.
Edit Note 2: So the main issue is the sale of the armor. Change the 200ms delay present to 500ms.
No fix for quest completion bugs. The quest list is faster than any option if and when it fails once in a while.
