Further to my question about 65 simultaneous connections. I had the
idea of running two copies of my stress-test program, to see if the
server still reported 65 players (and thus the server would not handle
more than 65 at a time), or whether it would reach 130 players.
Without wishing to bore you with lots of randomly-generated names,
these are my results:
2 Warrior Acilactred the Recruit.
2 Augurer Goniver the Understudy of Magic.
2 Thief Grodus the Footpad.
... etc etc ...
1 Thief Erauw the Pilferess.
1 Warrior Dweimas the Swordpupil.
1 Warrior Glemos the Swordpupil.

130 players.
It seems that simply running two copies of the identical Lua script,
which attempts to make 200 connections, results in 130 connections -
65 per copy. That seems to indicate that 65 is some sort of limiting
factor inside luasocket.
... time passes ....
Well, this is a laugh. This particular script *was* running on
Windows, so it seems that 64 or 65 is some sort of limitation on a
Windows program calling select under luasocket (or indeed, anywhere).
However when I ran it on a Unix look-alike (OS/X) it successfully made
200 connections, and interacted with them. Here are the new results:
1 Mage Clilarka the Apprentice of Magic.
2 Druid Ereranyth the Attendant.
1 Cleric Silara the Believer.
... and so on ...
1 Vampire Wiciradfrid the Apprentice of Blood.
1 Mage Tirangwen the Apprentice of Magic.

329 players.
This demonstrates the server can handle 329 players, the OS/X version
of luasocket can make 200 connections, and the Windows version made 64
each. Well, that sort-of adds up to 329, a couple of the bots got
killed. ;)
I think we can safely speculate that World of Warcraft is not
implemented using Windows Sockets. :P
