For those of you with pingboost questions, here's the old explanation of how the -pingboost options work, as posted by Alfred [mailto:[EMAIL PROTECTED] Friday, July 12, 2002:
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.

In fact, this old explantation is simply wrong, while was quoted many and many times on hlds_linux last year. Should be:
[...]
Mode "2" reduces this by using a different wait method (a select() call). This method reduces the latency to 10msec.
Mode "1" 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 :)

For those, who still doubts in my words - simply run strace on a hlds process and look on output.
