Okay thanks. I'll fiddle with pingbooster and see what happens :-) Chris ----- Original Message ----- From: "Geoff King" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, September 27, 2003 10:27 PM Subject: RE: [hlds_linux] High ping with DOD when servers get busy - not hardware related
Play should be ok unless the FPS starts to go below 30. As for the pingbooster, it's a command line option. Heres the original HLDS_Linux mail. -EvilGrin From: [EMAIL PROTECTED] on Sent: 13. July 2002 07:18 To: [EMAIL PROTECTED] Subject: Re: [hlds_linux] Pingboost modes... All the pingboot modes attempt to reduce the latency caused by the server. The default implementation adds around 20msec to each players ping (under linux). Mode "1" reduces this by using a different wait method (a select() call). This method reduces the latency to 10msec. Mode "2" uses a similar but slightly different method (and alarm() type call). Again, the result it 10msec worth of latency being added. NOTE that this method has the potential to hang a server in certain (terminal) situations. If anyone has used this mode recently (not the first test we did!) and it hangs please speak up. Mode "3" minimises the latency to the minimum possible level by processing a frame EVERY time a packet arrives. This causes the lowest possible latency, but can also cause extreme CPU usages (it does a complete frame for every packet, with each player sending lots of packets per second and 30 players this adds up to insane amounts of frames). Use this mode at your own risk, it will consume all available CPU, don't complain that cstrike uses too much CPU if you use this mode :-) In a future release this mode will be tweaked to let the admin balance latencies agains CPU usage (by processing a frame every N packets). There is also an external modules called "pingbooster" by UDPSoft (or is it UDPSoftware?). They implement something like mode "3". As this is an external module, and was built for an older version of HL (1108) it may not work properly any longer, and future releases may (accidently) break it. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chris Adams Sent: Saturday, September 27, 2003 9:41 PM To: [EMAIL PROTECTED] Subject: Re: [hlds_linux] High ping with DOD when servers get busy - not hardware related Hi, Here's what 'stats' gives me. No players so this is probably useless :-) CPU In Out Uptime Users FPS Players 12.67 0.00 0.00 114 2 49.80 0 I'm not sure what FPS should be, so please tell me if it's OK :-) As I said, it isn't a hardware problem (I have totally eliminated this through my own debugging), so could you go into detail about pingbooster? What is best? Or do you have any URLs with info about it? I won't be fiddling with the kernel since i'm a few thousand miles away from the boxes in question, and the guy with the servers isn't up to recovering from a broken kernel. Has anyone else had this problem and found that a software-based solution?
