Late to the game on this one, team. Sorry! Sounds like you’re sorted though. ? To make your consumer slower faster, try increasing the message rate… hopefully wouldn’t take 15 minutes in the future.
And yes, I use the -hm option all the time. Best thing is, you don’t have to use it alone: you can have all your other params: -cip -cu -ptl -mn -mr -msa etc., and then if you forgot how to do one thing, just add on -hm | grep <blah> and look for a feature or name of something in the giant help screen that’s displayed.
