Alt-F4 #15 - Investigating 1.1

Post by AlternativeFFFF »

This week, with 1.1 experimental just released, we take a look at two of the things it brings with it. First, Conor_ investigates what the new train stop limit allows him to do in his TSM-based factory. Then, Therenas explores what the multithreading update to belts means, both in theory and in practice. Careful, you might just learn something!

Thanks for the work on the multi-threaded belt logic investigation.

What CPU was this performed with? Is there any indication of performance on low- and high-thread count CPUs, and how well this scales?

Hi, author here, glad you enjoyed it!

Regarding your question, the measurements were run on a i5-8600k@4.8 GHz, with memory clocked at 2133MHz. I want to emphasize again though that the results are not very precise, and are only intended to show the general trend of the improvements.

Regarding scaling, I don't have any particular results to answer your question. In general though, I think the same heuristic for running Factorio apply. High single core speed is likely king, with memory latency and speed being the bottleneck in most situations, according to the devs. I can imagine that anything more than four cores has a rapidly declining performance advantage. For anything more detailed, you'd need to run further tests with a much more precise testing setup than me just using my PC :p
