Dead Men Racing on Wednesday night

[vobler]

Blimey, it didn't take long from a representative from the Church of iRacing to turn up and spread the gospel. :sideways:
 At least when you've told the Jehovah's witnesses to **** off a couple of times they get the message. :lmfao:

Well I did not like that very much. I am no ones representative and you are in no position to tell me to go anywhere.

In the light of some testing done by GPC tonight, the bandwidth setting seemed to make a difference. For Snetterton I've made the server bandwidth requirements 200 somethings as against 300 somethings

Hi Ron,

I saw your post and thought it was strange to reduce the bandwidth from 300 to 200, so I had a look at the manual ( if in doubt RTFM! ). The manual suggests that the actual bandwidth setting applied in the network tab when setting the server should be about 80% of the actual bandwidth available. i.e. if the server actually does have a 300KBs uplink speed then in the server tab you'd put about 240KBs, this is apparently so nkpro can start dynamically throttling the data speed before it busts the actual network uplink limits, which is apparently what will cause lag and warping etc.
Bear in mind that whatever the stated network uplink speed is you will never get the full amount due to network protocol overheads.

The manual also states that to host a maximum of 15 drivers you should have at least 262KBs available which would require an actual uplink speed of around 330KBs.
Therefore my conclusion is that, at minimum you'd ideally want a 350KBs network uplink speed which would allow a setting of 280KBs in the server tab for nkpro to use.

So having said that, do you know what the actual server uplink speed really is? Hope this helps?

Oh and BTW, please no self harming on race nights, whatever happens!!!!  

P.S. Don't want to patronise anyone, but just for clarity - KBs = Kilo-Bytes per sec, as opposed to Kbs = Kilo-bits per sec which is eight times smaller/slower.

I understand that. The trouble is, I think, (and I'm not alone) is nKPs doubtful net code. So going by the manual is a bit hit 'n' miss! Even the 300 figure was an arbitrary one.

The manual also states that to host a maximum of 15 drivers you should have at least 262KBs available which would require an actual uplink speed of around 330KBs.

TBH I have asked, but either I didn't understand the answer or was told 'sufficient'. I really can't remember. I'll ask again and ask for the answer in words of one syllable.

It's my throat and I'll cut it if I want to :narnar:

Or to do it the other way round, would it be possible to request that it is set to at least 350KBs for the netKar servers?

I can set it to what I like, I just want the right setting. I've consulted brains bigger and fresher that mine. Watch this space.

In the light of a reply from a bigger and fresher brain, I've upped the bandwidth to 550 kilomegabots/s. I just hope that's enough. :sad:

[XLR8]

Kilomegabots Rule!  :taz:

Lets hope this bodes well for Wednesday.

The nkP server (and all our others) share a 100Mbps pipe.

100 Mbps [Megabit-per-second]
=100000 Kbps [Kilobit-per-second]
=12500 KB/sec [Kilobyte-per-second]

So if nkP recommends 80% of the available bandwidth then that would be ...

=10000 KB/sec [Kilobyte-per-second]

That's a big number. Set it to 750 thingyjobbiewhotsits. That'll be plenty.

Hhmmm... just a thought then but, if the servers are all on a shared pipe is there anything else significant that happens on a Wednesday night around 20:30 to 21:00 because that was about the time that we had the problems at each of the tracks where the game crashed?

i.e. is anything else causing a restriction on the available bandwidth at that time?

Are there any network or server stats/logs available for those times?  :g:

If that's KBs then that should be roughly treble the recommended requirements according to the manual, so a big   :thumbsup2:  to that!

[OldBloke]

Absolutely not. We used to have discos on LFS when that was full on a Thursday but since we fixed our firewall issue that has been sweet as a nut.

Puff puff puff!  Right! 750 kilogramsofcoke/s it is. :eyebrow:

[XLR8]

WooHoo! - Kilogramsofcoke trumps Kilomegabots :yahoo:

So if the servers uplink is at 750 then the netKar network tab setting can be anything up to 600 Kiloelectroencephalogodzillagrams right?

Which should be plenty. :dribble:

The network tab settings is one of the things we tested last night. Made not one iota of difference.

[XLR8]

Ok, I'm running out of ideas now. Here's my last three -

A) Does anyone on the forum know how to do Voodoo?

B) Does anyone have Harry Potters phone number?

C) Is anyone willing to sell their soul to the Devil for better netcode?
