Follow-up Comment #6, patch #1739 (project freeciv):
a small analysis of the memory usage of freeciv (using pmap)
naming convention:
* freeciv server:
log_server-<version>-<# player>-<1 = connected + started>
* freeciv client (gtk):
log_client-<version>-<# player>-<1 = connected + started>
* <versions>:
S2_2 = something between R2_2_1 and S2_2
(on another system and no debug information!)
X1 = svn 17555 (before increased map size + player numbers)
X2 = svn 17568 (after increased map size + player numbers)
X3 = with patches for dynamically allocated players (126+2)
X3a = limit dynamically allocated players to (30+2)
* <# players>
1 = 'set aifill 1' (default map size [4])
30 = 'set aifill 30' (default map size [4])
126 = 'set aifill 126' (default map size [4])
126map = 'set aifill 126; set size 128; set generator 2'
== analysis ==
* memory for the executeable (SIZE column in the tables):

* there seems to be a lot of structs / static definitions which use
MAX_NUM_PLAYERS (bv_players?); thus the memory requirement is increased if
the number of players is increased (X1 => X2)
* on the client side the heap size is increased by ca. 8MB. Could this be due
to ./client/tilespec.c:311? ('player_borders[MAX_NUM_PLAYERS +
MAX_NUM_BARBARIANS][EDGE_COUNT][2];') If the number of players is reduced to
30+2 the memory requirement is similar.
