Wow, very kind of you to offer! I just wouldn't know how to be of any help. Honestly, I don't absolutely need the realtime capability myself. It looks like I can playback about 16 tracks while recording another 8 with a normal buffer size in Mixbus. For audio, many of us use the processing built into the audio card, such as the RME HDSP mixer. This allows us to keep a large buffer in the host audio program. But, a lot of people these days like to use synthetic sounds or samples generated by the computer and therefore need a low buffer (say 2-10 msec) in the host program so that when you play a note on a keyboard or play your guitar through an amp simulator, the processed sound is returned to the performer very quickly. So, again I was just curious to see if this capability was possible with Vector and maybe I could recommend it to someone else in this application.
I stumbled upon Vector and found that it is one of a small handful of distros that will write to disk without disrupting the streaming going on with alsa when running the software that I have written for recording. So it is true that there's something very efficient about Vector Linux! Thanks!
