Simutrans Extended Development / Re: Server performance: preliminary findings

How different from each other would they need to be; would a set of backups a few hours apart work?

The idea of training is detecting typical patterns within files of a given type, so I guess a set of backups would work perfectly well as long as there were players actually playing the game at that time.

Otherwise, such a comparisation would be quite pointless. It would be kind of "calculate the best way to compress a set of 95% simmilar files", "now use the gathered information for another file that is by 95% just the same".

I am afraid that I cannot download the reproduction case for this, as I get a 404 error. I should be grateful if you could re-upload this.

I am afraid that I am not able to reproduce this with the saved game attached: the locomotive is correctly in the drive by sight working method in the dead end section and the one train staff section in the loop. Is this not the behaviour that you are getting?

Thank you for the report: I believe that I have now managed to fix this. I should be grateful if you could re-test with the next nightly build.

Also, Freahk - how many would you need?

I don't know exactly but a few, ~5-10 should give us an idea if it's worth further investigating zstd training for our purposes or not.

Simutrans Extended Development / Re: Requirement for high_clearance_uder_bridges ignored on open water

Oh yes, it broke oil barge line on stephenson siemens server.

So there is now problem that no ships are allowed under low bridges. Oil barge does not have the requirement for high bridge, yet it cannot pass

Thank you for the report - I believe that I have also now fixed this. I should be grateful if you could re-test with the next nightly build.

If I read some more on zstd, It seems that the zstd can read also zlib file, so it would have backward compatibility without any extra effort. That is nice.

I wonder though how TurfIt gets more than four times of the datarate on writing binary files. Does experimental dump large tables at one point?

I suspect that it does: the routing data in large games can be very large, and these are in hashtables.
