In my experience, the latency configured for jack is the only noticeable latency on the system. I'd have to boot my kit to tell what my jack settings are, but the out of the box jack config on Fedora has fairly noticeable latency. Even on the very old hardware I use for my kit I was able to turn down the latency until I could not notice it. Actually, there is one other thing, if you are using USB sound cards for MIDI in and audio out, make sure they're not on the same USB bus. That caused unpleasant latency as well.
