Factors affecting game speed?

[Esme]

Hello!

Is there a handy list of the main factors that affect game speed, with regard to modded installs? If so, could you point me at it please? I know that having lots of parts in one area slows things down, but I'm unsure what other factors might come into play. I'm playing KSP 1.04 on 64-bit Linux, in case that's an issue, and I do not mind turning graphical effects way down if need be if that'll help speed things up. Is there anything other than using least posisble number of parts and turning graphics quality down that can help?

Thanks in anticipation,

Esme

Graphics quality, par texture resolution(also increases RAM usage?), game window size, the ground scatter (a big hit), aerodynamic effects (another big hit), lights (for some), many parts, lots of smoke and staring at celestial bodies at low orbits (might be because of ground quality too)seem to decrease the performance.
