I do not know about that "RH monitor" you are referring to, maybe it
does not display rates correctly. (I found 3 out of 5 rate estimators
outputing with a variance of over 10%) I can recommend you bmon [0]
which states the variance and can be used to a resolution up to
1/100s given the input source provides an equal or better resolution.

Very likely, especially due to the huge difference in requested and
achieved rate you have mentioned above. I hardly think this is a
problem related to HTB but rather some misconfiguration in your testing
process.
