How about the process of elimination? Some deductive reasoning and finding the truth instead of speculation.
For that to happen we would need the following:
1) A quite powerful server with adaptive clocking
2) 32 volunteers testing all extremes (max rate of fire [direct hit, particle hit], max particles per time [lrm20 boats throughout]) all with modified HP (like nearly infinite, so that dmg is actually applied)
3) Ability to monitor RAM/CPU usage over time
4) Ability to monitor particle counts over time (is there something like profile 6 for the server?)
5) Ability to monitor hit rate (volunteers should be positioned for guaranteed hits)
5) Several test runs at several clockspeeds plotted and analyzed properly
I think you get how much effort this will take. And I think, without the help of the devs its pretty much impossible.
