Like, say, if I were to encase my rail network with turrets because I'm sick and tired of biters getting caught on a big power pole and destroying it.
So yeah, there's no real easy way to get bots/supplies out to out to the 16k laser turrets surrounding my rails (which double as base perimeter). I suppose I could always make one huge bot network but that runs into bots being idiots so no.
I just wind up driving a train through every now and then to manually repair/replace things.

I don't mind the electric cost, but how will this do when the path from turret to supply chest is 1k+ tiles away? If I setup a handful of supply stations, can these turrets efficiently 'zoop' the repair packs where they need to go?
What about from just one central repair pack chest to cover a 2k*2k area? How many hops is too many and causes a UPS drain?

PS: I saw that post about it using repair packs on reddit and this looks fucking amazing. Can't wait to try it.

shouldn't be so bad, 1k tiles is only 10 hops over max distance roboports

IF you try it and its not that great, send me the save and I can try to optimize it

It's not as bad as I was expecting. Longest run over rails is about 2.5k, chunk based so repair towers are approx every 32 tiles.
So it's closer to 70-80 hops. (Intersections are a bit more spread out so those may incur more hops per chunk. (There's 274 total built right now.)

Anyways, wort-case (me shooting some turrets at that extreme end) results in script update of 0.4~ms for repair turrets. (But only when something is damaged, which isn't too often.)
Not a big deal for now as I'm only hitting 5-9ms for UPS depending on what's idle.

Proc is i7-6700k.

On my case I had to remove the mod due to ups issues during biter attacks.

I'm currently running a world with space exploration and some other mods, here's the save: https://1drv.ms/u/s!Ak4ek4pOHXIrgSLZd75TRWGI07Un?e=heMgWY

When there is a biter attack my UPS on my machine drop from 60 to 40ish.

For the time beeing I just use the 0.1.1 version which is fine, so my assumption is, that this has something to do with the "hopping" from one port to another.

Thanks for the save game, you're right the hopping is what I causing some performance drop.

Your save was really useful for me trying to optimize it, which I have done for the latest release.
