I.
DEDICATED VS LISTEN SERVER
There are two kinds of Purge
Servers: a Listen Server and a Dedicated
Server. Listen Server are servers that you
can also play on. It has fair performance
for 1-4 players, depending on your system
resources (CPU, RAM, etc.). Even on the
absolute top of the line computer, the maximum
number of players (including yourself) on
a Listen Server should not exceed 4 players.
A Dedicated Server is a server that is a
standalone server. It can support up to
64 players, performance depends heavily
on your system resources.
A Listen Server is started
by launching Purge.exe. Then hosting a game
with "dedicated = no". A Dedicated
Server is started by launching Purge.exe
to change your server settings (or manually
editing server.txt) then running PurgeServ.exe.
II.
BANDWIDTH REQUIREMENTS
The
single most important thing about running
the server is the amount of bandwidth your
connection has. You should not rely on the
numbers given to you by your ISP, rather
you must test your bandwidth to determine
it actual speed. Try DSLReports.com
for a speed test.
The
Upsteam/Upload speed is the vital one!
This the speed at which you can send
data. Upstream is almost always lower
than downstream/download. Having an upstream
of 128 kilobits per second and a downstream
of 1024+ kilobits per second is normal on
DSL or Cable Modem. In this example, your
server is limited to 128 kilobits. This
is because your server will sending more
data than you recieve in most modern
online games. Thus we do not recommend running
a server on DSL or Cable Modem except very
small servers (1-6 players).
Again, the upstream
number is the important one,
not the downstream!
Each player will need about
4 kilobytes/sec (or 32 kilobits/sec)
worth of upstream bandwidth from your server.
This number can spike or dip during little
gameplay, it should not be problem as long
your bandwidth is outputing consistantly.
You will also need to tell Purge how much
bandwidth you have. This can set under "Setup"
in hosting options or by manually modifying
the server.txt file. Remember this setting
is set in bytes, and not bits. Please for
the quick reference guideline below.

III.
LAG TROUBLESHOOTING
Most Purge players do not
experience significant lag with the latest
update. If players on your server are experience
lag, your server may be set up improperly.
1. Make sure you are running
the latest retail update.
2. If you are running a
Listen Server, try running a Dedicated Server
instead.
3. The computer running
the Purge Dedicated Server can not be
running anything else. Do not run IIS,
a web server, a FTP server, or anything
else on the computer.
ABSOLUTELY DO NOT play Purge (or any
other game) on the same computer as the
Dedicated Server. Also disable
as many unnecessary Windows Services or
TSRs as possible.
4. Make sure your server
bandwidth speed is set correctly in Purge.
If you overestimate your connection speed
Purge will drop packets and cause massive
lag. Please carefully run speed tests of
your bandwidth before telling Purge how
much bandwidth you actually have. Also make
sure your bandwidth reflects the number
of players you plan to support. Purge will
lag badly if you have too little bandwidth
for too many players. Remember, Purge will
not inherently know you connection speed,
you need to set it.
If you still have problems
getting your server to perform, ask for
techinical support here.
