You can use ping to check your delay rate to your server or to Gamestorm it is very useful especially for those of you adjusting your MAXMTU'S.

PING -- a basic TCP / IP tool for checking round-trip times.

Ping -- which you can find in your computer's Windows directory as "ping.exe"
-- is a simple tool that uses a special kind of TCP packet to generate what
is called an "echo request" from a remote machine. What Ping does is send a
message, then display how long it took for that message to get to the
destination and back (that isn't exactly what happens, but it's close enough
for an introduction). Picture it like a serve in Tennis: your Ping time is
the time it takes for you to smash the ball, have it bounce off your
opponent's flat forehead, then return to your baseline. The shorter the
response time, the faster the round trip. Responses are measured in
milliseconds, which are thousandths of a second. A return of 500 milliseconds
would indicate half a second.

Ping will also tell you if any of the packets it sent out were never
answered. It's common for some data to get "lost" in the Internet when things
get busy, and TCP/IP is designed to take that into account (within reason).
When no response is received to an echo request, Ping will display an
asterisk ( * ) to indicate that.

The output from running Ping looks like this:

C:\WINDOWS>ping gamers.gamestorm.com
Pinging gamers.gamestorm.com [206.15.217.106] with 32 bytes of data:
Reply from 206.15.217.106: bytes=32 time=218ms TTL=246
Reply from 206.15.217.106: bytes=32 time=216ms TTL=246

Note that by default, Ping sends four requests to the host you specify on the
command line. In this case, that's a GameStorm server called
"gamers.gamestorm.com." Since this machine is on a network very close to our
game hosts, it will give you a fair idea of how your actual GameStorm game
connection might perform. The only thing you really need to look at is the
"time= " column. For optimum gaming, you want Ping times of less than
250-300ms. You also would like your Ping times to be fairly consistent, like
the ones above. If you run Ping a few times, and the response times you
receive fluctuate wildly, or are greater than 400ms to 500ms, you might
experience lags or warps in the game, and possibly even complete
disconnections ("dumps"). Poor performance like this occurs when the
connection between your ISP and our game host is congested. This congestion
is OUTSIDE GameStorm's control -- we make sure the GameStorm network has LOTS
of free bandwidth!
