for those of you who waited forever for the Linux binaries that were never made, swbf1 ps2 server works in WINE. though there's a problem with the maps loading slowly. winehq lists the swbf2 ps2 server as a compatible application as well.
as for cpu usage, the dedicated servers don't really use much system resources...
I've monitored bandwidth usage using OnlineEye. The PS2 dedicated server uses approximately 60 kbits/s of upload bandwidth for one player, and 10 kbits/s download.
additional players use slightly less bandwidth progressively, so that for example 10 players can get by on 570 kbits/s upload. download bandwidth is rarely a problem.
Is there any way to modify shortcut properties so they can take a longer command line? I can't fit the command I need in there.
