What helps me tons with questhelper and reduceing the lag is to reduce the route calculation on all the other ones to 20% and keep high on the main.
That way it still tracks all the others quest and what not :P

Only thing that might be kinda annoying is its take a bit longer for it to register when one or more have completed the a quest not that big of a deal.

/qh setting will popup a menu
By setting /qh hide on your foloower (or press the button questhelper on the map) you will stop route calculation on your followers (they dont have to). But route calculation will continue on your main. So even less stress on the system. That is what I tried to explain with the first post.

The completion of quests is lag between interfacing from alts to main. I believe they are always the same. Even with processing on on the followers.
