After the increase of the number of players and the map size I did plan a check of the memory requirement of the different freeciv versions. I finished this now and the attached pdf files shows some results.
The first two pages show the RAM used by the server as listed by pmap. A savefile with the default settings and aifill = X, map size = Y at turn 100 was loaded. Only one value of X or Y was changed while the other was set to 10. The requirements increase fro release to release; but with 2.3 it goes down for bigger maps. I also tested a game with aifill 100 and mapsize 100 - the server allocates up to 900MB RAM! The last two slides show the size of the savegame. For small number of players and map sizes is is OK. But increasing these numbers the size of the savegame increases and, if both are set to 100 the uncompressed savegame reaches a size of over 100MB. For such savegames the time needed to compress the data is significant. For the client, the memory consumption is increased from 1.14 to 2.2 (xaw to gtk2). After that, nearly no change is visible. The client uses up to 500MB, mostly for the graphical toolkit. If there are questions please ask. -- Matthias Pfafferodt - http://www.mapfa.de Matthias.Pfafferodt <at> mapfa.de
