I have a cable modem and the core.ini for a cable modem.
I have a Celeron 300A o/c'd to 374Mhz, 128Mb of Ram and a Monster
3dII(8Mb) using Diamond's original drivers, but have things a little
tweaked with Tweakit. I have the game at 800x600 res so I get a pretty
stable 36fps most of the time.

I was getting a Latency reading of 167 most of the time to Tim's this
afternoon (btw, does this mean a ping of 88 times two for each direction
of travel, or 167 one way?).

I kept getting disco'd (man I used to go through this playing Warbirds
with a dial up connection) about every two or three laps. I noticed
that a fair number reconnected every time I did. Was I getting pushed
because too many people were on-line on Tim's server?

I started the race and even had a half decent start before getting
bounced by a Lotus that had started ahead of me on the grid but spun
wildly across the track after hitting a wall. I went airborne and
landed but continued. At this point there were no other cars and I kept
the throttle pressed to go down the straight. No cars I figured to be a
bad signal... in Warbirds loss of other planes meant a "yellow beacon"
which indicated packets lost and an imminent disco unless things turned
around quickly and packets started arriving. Sure enough, a few moments
later I disco'd and couldn't get back in because the race was being run.

Does it sound like the problem is on my end, the server's or just too
many players? When the race started there shouldn't have been any more
players joining so I thought that things would be pretty safe then.

Is there anything I can adjust? I can't play with DUN to mess about
with Fifo settings, compression and error control because I have a cable
modem. It didn't give me any problems with Warbirds, and dial up
settings had to be configured for that too (ie. the cable without any
adjustments worked at least as well or better (certainly in terms of
ping times) than the adjusted dial up settings).

Can someone make a utility that measures packet loss?

Thanks in advance for any help!

Cheers,
Gian Vitzthum.

This could very well be a problem on my end as well. As you know, cable
modem upload/download speeds are not constant and changes every minute as
others on the same cable modem 'node' could be downloading a file which
lessens the amount of bandwidth that I have for the server. Last I heard,
there were 8 others on this same node as I am, and I really dont know thier
downloading habits.
It is possible that one of those people are doing something on the net and
taking away from the allowed bandwidth, causing some packet loss and

will make me stop.
Each person connected to my server takes up 24k of bandwidth, or at least
that is what the manual says. Times that by 20 players, and we have 480k
transfer a second. That is a lot and it is easily cut into if someone else
on the node starts downloading something.
Keep trying, evening are better of course.

That would be me :-( ... sorry about that ... Gotta keep practising those
starts.

I had no problems. I connected from Finland with 64k ISDN, got the pole but
blew the start ... there was some warping with other cars but I've seen
worse. Even the start was pretty fluid .. or would've been without me
spoiling it.
My latency reading was .333.

Sorry i can't be more help to ya ...

Hi Tim,

Gotta congratulate you on having the busiest GPL server (that I know of :)

Ummm. Its actually calculated in 24000bps <Bits per second>That would be
24000bps / 8 = 3000 characters/s which is 3k/s

(Remember the 3.2k/s download speeds you would get when downloading
files from the internet :)

3k * 20 people = 60k/s upload speeds required.

My cable modem usually gets 20k/s upload speeds but is installed using
Channel 0 on your TV dial -- not the entire bandwidth of the 'cabe' itself.

I would think you have a dedicated 'cable' line for the modem to get
such a fast upload rate (480k/s) WOW :)

88ms in each direction, for a total round trip of 167ms -- my best was
111msround trip :)

I thinks it's Tim's connection -- lost packets and such.
