In the linuxthread faq, they +said that an application should not create more than 100 thread. In this +case, we have to forget the solution where each +socket is on a thread and use a blocked receive(). The problem is that +select() is quite slow and if we have only 100 thread, +each thread needs to manage, with a select(), around 50 players and we ll +lost lot of time to create the array for the select() +and check who have wakeup the select(). + +Vianney Lecroart +--- +lead network programmer / nevrax.com +icq#: 6870415 +homepage: <A HREF="http://ace.planet-d.net">http://ace.planet-d.net</A> +www.geekcode.com: GCS/E d- s+++: a-- C+++$ UL++ P- L+++>+$ E+>- W++ N+ o?
