I think the AI is unusually slow in this scenario. At the moment the Europe
1901 is not usable on the production server.
Possibly the AI will have to behave differently with a very large number of
cities and units, for example perform less calculations for each unit if
the number of units is above some threshold value.

Follow-up Comment #4, bug #24018 (project freeciv):

In case of aitoggle, at least, the time is spent in assess_danger(), called
for 46 cities player owns, each taking seconds to process.

Yeah, I took "George V" to enter the game. Tried to aitoggle him off to have
an all-AI game, and that simple *aitoggle* took extremely long time. This is
something to investigate.

Follow-up Comment #1, bug #24018 (project freeciv):

Yes, I can confirm that this is the issue with Freeciv-web as well. 
The freeciv server process is running at 100% CPU usage.
Attaching a backtrace generated with gdb when attatching to such a process.

Are the AI players unusually slow for the number of units and cities they
have?

It's unusual to experience this right from the start of a game, rather than
having one's frog boiled  as the
game progresses.

Details:

Slow enough to give the impression that the server has locked up. This didn't
happen before patch #6493 made all players AI controlled by default.

Andreas: Could you check if this is the issue in Freeciv-web too?
