Stefan, are you sure of those speeds? A dial up would give you 56k up and down. Your speeds seem very low. Some how I seem to remember 28k per entrant as the number for GPL. That would mean a bit over 500k for a full field.
Sorry for the confusion. My connection is fast.
I had used dots (".") to separate the decimal places and not comma's (",") that you use in English.
In German: "This will cost you 999,50 EUR".

I have updated my first post accordingly.
I think I need to explain why I want to limit the bandwidth of GPL on my server.
I know that GPL is not bandwidth hungry as GPL was released in 1998 when we didn`t have fast internet yet.
I do not need to limit the GPL bandwidth because I have a slow connection. My connection is fast (see post #1 of this thread).
At some GPLRACER league online races we had very bad lags, or let`s better call it "spikes" as it was really heavy and made it impossible to race anymore online.
But strangely we did not have it all the time.
I have spent a lot of time over the last months to search for the cause.
I have checked:
- Windows 10, with the latest Windows 10 Spring Creators Update Build Version 1803 installed. All apps and services are deactivated that do not need to run on the server
- is the server (hardware) damaged, maybe the network card on the mainboard has an error?
- does the cable line of the provider not work as it should?
- is my network cable damaged?
- canged the Network/Server settings in GEM+ to lower 3/132 instead of full 3/384
- .... and so on, anything you can imagine
All without any success.
Finally we found out that it is related to my PlayStation 4 (PS4). When I was streaming movies via Netflix or Amazon Prime Video while we were racing we had massive lags (spikes). You may now say, well, that is logic, but strangely this didn`t happen all the time. We had online races while I was streaming a movie on the PS4 and we didn`t have any lags on the GPLRACER league server.
But the last time I had tested with Paul Skingley (thx for your time!) we had massive lags (spikes) when my PS4 was streaming a movie. When I stopped the movie streaming on my PS4 the lags (spikes) where gone.
I searched the internet and found many posts of PS4 users (and also PS3 users) who had the same problem.
As soon as their PS4 is downloading something all other devices in the home network have lags and almost zero bandwidth.
The PS4 takes the full bandwidth of your home network and sadly it has no setting implemented that you can limit the bandwidth of your PS4.
Knowing this I used the hidden option on my FRITZ!Box 7270 router to prioritize devices in my network.
So I have set my GPLRACER server to "high" priority and my PS4 to "low" priority on my router.
But you guess it.... it didn`t help anything. Even with prioritization of my devices we still had massive lags (spikes) when my PS4 was streaming a movie.
Then I had the idea to limit the bandwidth on my GPLRACER server (with the software cfosSpeed https://www.cfos.de/en-gb/index.htm
) and set it to half my overall bandwidth I have for upload and download.
And surprisingly all lags (spikes) are gone now.
Therefore I wanted to know the maximum bandwidth that GPL is using for up-/download as I do not need to set it higher than required.
According to Roberto Teso`s great list I take the highest values that can be possible depending on my BW patch and 36/60 FPS settings:
- maximum GPL bandwidth clients server download = 33600 Bps = 269 kbps (total kilobit per second) ~ 34 kB/s (kilobyte per second)
- maximum GPL bandwidth server upload = 7680 Bps = 62 kbps (total kilobit per second) ~ 8 kB/s (kilobyte per second)
That is really not much for a cable connection.
As I have plenty of overall bandwidth on my cable conneciton I thought of setting the limit within the software cfosSpeed to 100 kB/s (kilobyte per second) for up- and download. But then the internet connection is so slow that it will take ages to download any Windows updates. And even standard surfing becomes very slow. That does of course not make any sense.
Ergo I will stay with my limitation settings within the software cfosSpeed of half of my overall bandwidth (see screenshots).
Thx for your help!
