Improved save-game speed by up to 2x depending on the save file size.

Not gonna lie, I would LOVE to see a writeup on how you managed this. (and the current roadmap/status in general. Been missing the FFF more than I thought I would.)

I'd also love to learn more about the optimization to save-game, is the "up to 2x" reachable on smaller or larger save files?

PSA for people playing with Industrial Revolution 2.0: game crashed on launch with Not reporting a bug because I know IR2.0 modifies tips-and-tricks, I'm assuming this is not Wube's fault (especially since there was no migration message). Log on pastebin if anyone is interested.

EDIT: I fiddled around with the mod files and fixed the issue, you can do it too by extracting `/IndustrialRevolution_2.0.4/code/data/vanilla-tips.lua` from IR2's zip file, opening it in a text/code editor and adding those two lines in the middle: Repack the modified file into the zip, restart your game and it works like a charm

@Zeroji - thanks so much for sharing!

I'm in the same boat. The FFF was super interesting when it got into optimizations.

I Also miss the FFF much more than I though. I have lost touch with the game state and direction, after they are not there every Friday.

Please consider bringing them back, or giving public access to you sprints or backlog if it makes sense. I loved the transparency and it is what have keept me playing after owning factorio from the early days.

I assume it is related to the messy interaction between overhaul mods and the tips and tricks system, so you might see a break every time there's a new tips and tricks added.

please tell us more. what are the conditions to see improvement?

from my testing here, "up to 2x" refers to small save file sizes, and large saves aren't improved much, or at all. it might even have a slower serialisation pause.

Other way a round; the larger the save the more savings there is. Smaller saves aren't effected and save at the same speed.

..

I have a 547MiB space-exploration save that is slower after 1.1.14.

edit: it might have just been disk contention.

Comment on the update post on the subreddit said it was multithreading compression when saving.

Rseding91 wrote:Compressor improvements. Specifically; compressing on multiple threads.

And I thought about other compressors briefly but it doesn't matter since with this change compression is no longer the bottleneck in saving. Iterating the world state and figuring out what bits and pieces to save is the bottleneck.

Weekend fix; Nice!
