Most of Factorio is actually single threaded.

I suggest providing a log and other information + the screenshots requested in this thread viewtopic.php?f=7&t=51319 .

As I said above most of the Factorio code is single threaded (only uses a single cpu core). (There are some parts of the code that do utilise multiple cores, but much of the code is single threaded). Fully utilising one core (in your hyperthreaded i7-6700HQ) would be 12.5% in Windows task manager. 18.4% means Factorio is averaging about 1.5 cores.

There is nothing that stands out to me from the screenshot/logs. I think you have just built more entities than your computer can update 60 times per second. (The game update is taking over 37 ms per tick, most of which is the entity update step at 27ms, followed by electric network at 3.5ms).

There are probably some optimisations you can make that would help (eg replace some of those pipes with fewer underground pipes segments). Look at some of the megabase threads and/or search the forums for posts about ups optimisations.

There is nothing here that suggests to me his computer is a problem. (Sure a faster desktop computer with a higher clock speed and faster ram would give higher fps/ups, but I doubt it would get to 60 fps).

You can gen much better fps if you disable Factorissimo.

so I need some single thread perfomance beast in order to keep expanding thxs for reply

Even if you got a cpu with double the single threaded performance, that probably wouldn't double your ups. Rseding has said that much of Factorio's code is bottlenecked by memory bandwidth, so you will probably still be bottlenecked at less than 60 ups.

A better alternative is to migrate to a more ups friendly design. Eg solar + accumulators is essentially free from a ups perspective, and much more ups friendly than nuclear or boilers. Small self contained bot networks reduce the average travel distance per bot, and hence need less bots in flight which is more ups friendly than larger bot networks. Similarly reduce the number of pipe segments as much as possible. Use stack inserters and direct insertion where possible (minimising the number of inserter swings). Chests are more ups friendly than warehouses. (Note I haven't seen your savegame, so I don't know which of these suggestions, if any, will apply to your map).

My favorite example of a ups optimised design atm is https://www.youtube.com/watch?v=Av8DZo368Jw . 10k science/sec at roughly 60 ups.

here my mods and save games can you take a look ?

I had a quick look. (Disclaimer: I'm not familiar with all the mods you are using, especially Youki Industries, so this is all general advise. Really you should look at the video I linked earlier and/or the associated reddit post https://www.reddit.com/r/factorio/comme ... _megabase/ and/or download the map, and/or look at other UPS optimised megabases. I'm also not an expert on optimising for UPS).

I would focus on reducing the number of active entities (crafting machine/chem plants/refineries/inserters/pipes/labs/logistic bots/belts etc. Also replace segments of normal pipe with undergrounds, since this reduces the number of active fluidboxes).

I'd redesign the base to make more use of productivity boosting modules paired with speed beacons. This has a few beneficial effects. Firstly the productivity modules means you need less input resources to produce the same amount of output resources. Using lots of speed beacons means you can do that using less assemblers, and fewer inserters/pipes etc to support them, plus shorter average bot travel distances.

Some notes after using the VS profiler to profile factorio whilst running your base.

[*]FluidBox::update 15.15% of total CPU time. (This is why you want to minimise the number of pipes/fluid containing entities as much as possible).
[*]CraftingMachine::update 8.85% (Again minimise the number of crafting machines/chemplants/refineries etc).
[*]LogisticRobot::update 7.89% (In vanilla you typically reduce the number of active bots by reducing their average travel distances, and you do that by having small dedicated logistic networks, rather than one large network).
[*]Inserter::update 6.54% (Less assemblers means you don't need as many inserters).
[*]LogisticNetwork::findBestAvailableRobotForLogistics 3.11%
[*]Lab::update 1.88%
