Srcds - Perfect server and still choke, im starting to think its the program now

[spadez]

Ive setup the perfect server, high end hardware and new install of windows2003 server. Created a new server with TCADMIN, its the only run one running on the box at the moment.

However, for an 18 man at 100tick im still getting around 6 choke average. Is choke bad, what exactly does it mean, is it server side of client side, because different clients are getting different values.

How can i calculate the vaules for the server update rate etc in a hope to lower it.

Thanks for any help you can give,

James

Well basically choke stands for: The amount of packets in line to be sent to or to be received by the server. It doesn't do much but lower the tickrate, too much choke will then again result in a tickrate THAT low it will lag, mostly this happens when you get to 50+ choke. (depends on the tickrate)

So as long as it stays low there won't be problems, however it's a "bad" thing in most clients eyes and it doesn't look nice in the netgraph.

Choke can be both server and client side, on the server side it's caused mainly by low rate settings, super tickrate drops are usually caused by CPU stress and high pings are caused by bandwidth shortages.

On the client it's also caused by rates 90% of the times, when there's a bandwidth problem you'll see all symptoms (tickdrop, choke, loss and high ping).

So make sure your client settings are as follows:
cl_updaterate 101
cl_cmdrate 100
rate 25000

Make sure the server has this:
sv_maxupdaterate 101
sv_maxrate 25000 or even better 30000 (30k is max, only needed on 100 tick in some rare situations)

Since you are running at a box I assume you have a 100mbit port, thus you can use max settings (see above). normally you can calculate sv_maxrate with this formula: bandwidth(kbps) * 128 / playerslots
So for 100mbit that would be: 100x1024 (to make kbps from the mbps), 102400 *128 = 13107200 / 18 = sv_maxrate of ~728177 (since the maximum amount you can set sv_maxrate to is 30000 you'll have to use 30000 )

Actually, sv_maxrate was increased to 1 megabyte back in the June updates.

Best for LAN play though.

lol talking about overkill, there's no possible way you can get your bandwidth higher than 30kb/s per player 25 is HIGHLY rare.

Thanks for the help guys, it turned out to be a mix of my client rates and server rates.
