    And what's the difference between 'k' = kilo and 'K' = kilo? ;-)

    An uppercase is a 1024 multiplier. See the first post, I added a link.

    So just to confirm the bandwidth requirements are 768kbits per car up to 30 cars.. 23000 bits in bytes / 8 = 2875kBytes..

    So a 2.8Mbit up connection will handle 30 cars.. Impressive considering the lack of CPU and RAM usage too.

    It won't handle them. It'll JUST handle them, if NOTHING ELSE is going on whatsoever.

    I always thought that depends on context. K or k... with apples that would be 1000 and in IT it would be 1024 but I might be wrong.

    @ZeosPantera
    No... you need at least ~23Mbps (or 23Mbit/s if you want that way) upload.

    I typed 1000 first but fixed it before you replied.

    I've read your post when there was already '1024'

    That some serious reqirements. To host a 70-80 driver event you'd probably need 100Mbps upload.. that's typical LAN speed!

    Huh? 30 = 23Mbit, not bytes...

    No. The server needs 22,5 Mbps upstream bandwidth to handle 30 cars.
    768 kbps * 30 = 23040 kbps = 22,5 Mbps

    Hmm. I'm not sure about initial calculations.
    Tim, you said that for 10 cars it is about 96kbps.
    It means that data amount to send containing info about single car is about 9,6kbps.

    It means that data stream of 30 cars should be 30*9,6 kbps = 288 kbps. Sending for 30 cars results in 8640 kbps / 8,6Mbps.
    What data is contained in additional 14Mbps overhead?

    Yes. Where did I say anything about bytes?

    768Kbps... 1000 bits per second. Are we talking same speed?

    For me, "typical" LAN is still 100Mbps (100 Megabits, which is 12.5 Megabytes) even though almost all of us, with modern PCs, have onboard 1Gbit cards... maybe you thought, by saying "typical" I meant 1Gbps LAN (which is 125MBps - MegaBytes)?

    obviously this is the server sending info on the cars to the other cars. The more cars, the more sending out. It's exponential growth, not steady growth.

    Ok, finally clear in my head...

    768Kbps *30
    = 172.80 MB/min
    = 2.88 MB/s
    = 23.04 Mbps
    = 2.75 MiB/s
    = 10.37 GB/h

    My home connection is 0.92 Mbps upload, to put that in perspective. So I won't be doing much hosting. But I am on the cheapest package my ISP offers right now.

    So you can host race with 10 car

    Maybe you should mention rFactor 1 server specs then add that rFactor 2 will eat 25 % more per clients or whatever this is.
    So people with their rFactor 1 references will know that they will be able to host what they use to host minus 25 %.

    I used to host non dedicated server with my 1024 kbps, i used to host 15-19 people. I guess in rFactor 2 i will able to host 10 people max.
    Dry conditions should cost less than rainy, anyway i'm curious to see for myself with this beta.

    Too bad economic crisis slowed down in France the Fiber Optic plans, 2012 and still nothing.

    Yeah my parents still don't have the high speed they were supposed to get 5 years ago in the UK. Parts of the USA are really bad, too. I can get very fast download, but the upload is sooooooo sloooooow!

    I get what you mean, but I'd rather people work off these than rF1 data.
