It's not clear that with 2.6 this is necessary or desirable. I'll let someone who worked on the new thread and/or futex development say more if they will, but I'm reasonable convinced that in most cases the kernel will do it better. | | Take a look here for more a comparison of several available methods : | | http://www.kegel.com/c10k.html | | epoll is compared to other methods with numbers here : | | http://www.xmailserver.org/linux-patches/nio-improve.html | | Cheers, | Willy | | - | To unsubscribe from this list: send the line "unsubscribe linux-kernel" in | the body of a message to majordomo@vger.kernel.org | More majordomo info at http://vger.kernel.org/majordomo-info.html | Please read the FAQ at http://www.tux.org/lkml/ |
