Game stutter at 270mb unallocated memory use.

[Arugela]

I have this really annoying stutter. I'm making a big plane but I'm wondering if there is a way to get rid of this somehow.

I have 1287mb reserved ram. Whenever it hits 270-269mb it pauses and jumps back up to 289-290mb. It's in an endless cycle. This causes constant stutter while working on my ship and it causing a lot of annoyance.

What is this and is there a way to make this not stutter endlessly? What is the alocated memory. Is it the cpu cache or is it system ram? I'm not really sure.(nvm it's over 1gb. It must be system ram.)

Specs:

KSP latest version(steam I beleive.) 1.5.1.2335

Fedora 28 Latest kernel.

Phenom II 1100t

16gb 4x4gb 1600 ram (9cas)

GA-970A-D3 board?

10603BG (410.73 drivers)

No over-clocking or anything(btw, would that help in this game? I can easily get up to around 4ghz.)

I've been disabling my swap on linux. I think it was accessing but turned it off to get it to act a little faster and I think it helped. But I still get this annoying stutter. This is a large ship but I'm wondering if there is a way to get rid of the stutter or figure out what it is. It went from 1287mb to 1342mb reserved memory but it's still having problems. Although I think it's a little less now that it increased it. It keeps counting down from 290ish mb unallocated to 270ish mb unallocated then dumps some and goes back causing a stutter. the value of unallocated memory is the same regardless of the amount allocated from what I can tell.

Edit: I was wrong. It can change when it stutters. It's was just in a loop at the same 270mb at the time this occurred. Would it help if it had the option for more ram? Or if we had the option to increase it. What is causing the stutter?

This stutter causes lots of problems like causing the mouse to miss do things and rip off parts or stop you from counting spaces to keep parts symetrical. It's pretty annoying if you are trying to be precise or timely. Caused me to reload a ship way too many times to count and start over work on aspects of my ships. Sometimes it makes it almost impossible to move stuff around in general depending on how aggressive the stutter is.

Is there some sort of memory timing that could be tweaked to make this stutter stop? Or is there anything else we can do on our end to help reduce this. Besides lowering parts count or whatever on our ships.

You could try the MemGraph mod:

I'm going through the ram timings and figuring out what I can trim down. So far I put it into ganged mode instead of unganged mode and it's pretty much resolved the stutter. It happens, but at a much reduce effect. Unless I just haven't caused it sufficiently yet. This may help resolve it though.

It may have slowed down general performance though. I think my 1000 part ship is flying a little slower than normal now. I'm at 13 seconds per in game second. I think it's normally less. But I could be wrong(it may normally run this slow. It may even be an improvement.). Upside/downside I guess.

Also the timing between the engines starting went back down to what it was before the 1.5ish patches. It had regained a pause and this makes that smoother again. From what I've read ganged is better for single threaded games. I wonder what changed to make it pause longer in unganged mode.

I've been reading that thread. Have to finish reading that then shore up the rest of my memory timings.

Edit: NVM, the stutter came back but it's a little different in that it is hard to grasp nodes as opposed to move them. Might be a little better though. Hard to tell. I think pauses from engine start and time for a plane crash to break up has increased significantly. And the pauses are shorter in general.
