[3.3.90.7-dev] seems unstable, especially for the Qt6 client — I will update the patch to future releases as needed.

I will also address reasonable recommendations.

patch reduced and updated.

I realize that I am not communicating worker-task-creation between client and server sides. Can you recommend a starting function to use?

I started this endeavor with a large map that had over 10K autoworker units that took 18 hours to complete. I found that most of the delay was due to the limited 5 levels of recursive calls finding the "best" task.

Removing the recursion, and choosing the closest task is the crux of the proposed speed improvement.

Additionally, I took the liberty of changing the autoworkers to be more autonomous according to my own personal sentiments. Before, the user needed to direct, by hand the autoworker activities, city by city. Proposed is, for the autoworker to follow the governor and build roads and farms automatically, maximizing food or shields and respecting resources. If my personal sentiments strike accord with other stakeholders, it could be embellished to follow the city's governor more or less aggressively. E.g. no transformations, or cultivations, unless the 'food' setting for the governor is above 20. E.g. no mines when shields is below 5.

Attached is a 1,000 autoworker saved game with the following characteristics:

Unoptimized
3:   Workers: 0.639994 sec turn, 0.639993 sec game
3:   Workers: 0.491397 sec turn, 1.13139 sec game

Optimized
3:   Workers: 0.011371 sec turn, 0.386664 sec game
3:   Workers: 0.011157 sec turn, 0.103477 sec game

This is a 50x performance improvement.

Evidently, this is not a linear improvement, affecting larger maps more significantly. I also suspect that, other than AI, users might not be using large numbers of autoworkers. But, even with mostly AI usage, the server performance for large maps will be significantly improved.
