[CentOS] Desperately need help with multi-core NIC performance
Hi, I am running a VOIP application on Centos 5.3. It is a 16 core box with 12 G of mem and all what it does is passing packets. What happens is that at around 2K channels running g711 ( 64k) codec, all eth0 is used up and no more traffic can go through. I have checked google and it talked about interrupt scheduler. does anyone know how to configure the kernel to allow it to use all CPSs for socket transmission of UDP packets? Any pointer will be greatly appreciated. pete ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Problem with running Centos 5.2 on Dell Optiplex 330
Hi, I am havind deep trouble with a bunch of our newly arrived Optiplex 330 as it can't run Centos 5.2 property. The installation works fine, but when it boots up, it can't be connected to the network. I am getting error saying " link is not ready" when doing system-config-network. I check lspci and it can detect the network controller no problem. The light next to the cable is also on as well. Does anyone know how I can fix this problem? We should have bought just one and see if it works before buying more, and now we are stuck. Could someone please kindly give any suggestion? Any help will be greatly appreciated. Best Regards, Pete ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If one of the systems goes down the whole NFS cross-mounting makes the other systems somewhat unstable. It's a known issue and I believe you guys are aware of it but I just had to see it myself. What would you recommend? What is the best practice for doing that? NFS and automount.
