Hi,
There are not built in performance monitoring tools, however you could use the host operating system tools to do this (like Windows task manager). I’ve found that in general performance is better with multiple translators as MT Pro can decide if some can be done in parallel using different threads. On the other hand, translators are extremely fast comparative to the much slower speed requirements of MIDI messages so I usually opt for less translators and more rules to simplify the code and seldom run into performance issues (unless I messed up how I structured the rules or translator order).
