Hello,
Well, the problems you described previously had nothing to do with bus speed. You had incorrectly defined read/write addresses, or missing read addresses, and some stuff messed up or misconfigured on bOS.
Furthermore, KNX TP allows for up to 50 telegrams per second under ideal conditions, which is a pretty high telegram rate. So if your bus is "talking too much" something may be wrong on your installation and you need to double check that. You can check that by analysing the Group Monitor on ETS and see how the telegrams behave, like if several telegrams are repeated or end up lost, etc.
I have some "complex" installations, with several bus couplers, and never had to mess around with write telegrams per second. But if that worked for you, perfect, problem solved.
Best regards
