I'm using 100/10mbit connection and I'm wondering how many connections it can handle before it starts lagging. I guess it depends on what "rate" i use at the servers, but if i go with default rate...

My guesstimation is like 100 users. 1000 Kbyte upload / 10 Kbyte rate = 100? I'm not sure though, hehe. www.facebook.com/QuakeWorld

But... i only have 10mbits up... ? Woudn't it mean only 10users?

Hmmmm
10Mbit = 10,000,000 bits = 10,000,000 / 8 Bytes = 1,250,000 Bytes
Your upload / users rate = 1,250,000 / 10,000 = 125 users.
Please correct me if i'm wrong, someone. :rolleyes: www.facebook.com/QuakeWorld

So rate 10k means 10kb/s duplex? I thought it was 10kb/s combined.

it's a combined rate of upload and download capacity http://slip.4.pl/ - unblocking myspace facebook firewall

here is the math, but remember, this is just theory IE if your upload rate is around 1152Kbit/sec (I have roughly that on my BBB 100/10) then your server can handle 1152*1000/8/8000=18 clients that is 8 players and 10 spectators, if you put maxrate to 8000.

If what goqsane says is true a 10mbit line can handle around 200 clients. Ie more than the playing population currently.. Term, 10mbit=/=1000kbit.

BBB 100/10 ? 100mbit/10mbit? Or that some price?

"BBB 100/10" is 100Mbit down and 10Mbit up yes, full duplex ofc, I don't see how you can have half duplex and "100/10". In reallity I download stuffs in ~5MB/s and upload in ~1.4 MB/s (that is from ftp.se.kernel.org, I just tested).
Error: seems I mixed up bits and bytes yes, tnx, it should be 18*8 = 144 clients

thanks. seems like i have ping issues for my servers anyways. My server is a 2.53GHZ with 2GHZ 400Mhz DDR RAM. So i could set up some servers if someone is intrerested. But... Seems like the ping isnt good enough? mustalainen.se:27500

25ms + some pl spikes from Finland. I'd suggest that you'll switch to KTX and the latest MVDSV. Those won't help with the occasional lag though

I'm using 100/10mbit connection and I'm wondering how many connections it can handle before it starts lagging. I guess it depends on what "rate" i use at the servers, but if i go with default rate... QW clients at 77fps can consume anything between 5kB/s - 27kB/s of bandwidth depending on the situation (and if the client's rate allows this). The max QW client download rate was tested with qizmo/netmon when more than one people were shooting with nailgun in amphi/dm2 corridors so that the maximum amount of data was sent (it was about 27000cps (or byter per second)). You seem to have 10Mbps upload which is a bit more than 1100kB/s transfer rate. A quick division gives me the result of ~41 at the max throughput (41*27kB/s=1107kB/s) which is almost all of your connection's upload bandwidth consumed. As I said, this is the situation when all the clients are having massive transfer rate from server to client and will probably happen very seldom (dm3 4on4 pent fights for example). I don't know the point where your connection begins to gain lag when sending data, is it 50% of the max upload or is it 75% or whatever is it. I guess your server(s) won't suffer from lag if there are 20 to 30 people playing with /rate 50000.
