For things you're building, if you have access to XML modding a good way to reduce lag is to set 'calculateDrag' to false and 'disableAircraftCollisions' to true on parts. Knowing this game's physics it's risky to remove drag on everything though, so do so mainly for little details you might add.
Bro im using a handphone and why is your PC cant run past 300 parts?

If only I had found this BEFORE making two tracks worth 2400 parts between them....
ahem
