Linux SMP network performance measurements

Hello, a recent article (http://www.ibm.com/developerworks/linux/library/l-scalability/?ca=dgr-lnxw02FasterLinuxNet) gives some measurements on various tweakings of an SMP machine with 4 Xeon processors (it *shows* a nice improvement when using more CPUs and more bonded Ethernet interfaces).

diskless boot of a PXE-compatible machine : finally done !

Hello, this a simili victory report : the PC now boots via PXE (this is a Motorola rack-mount PC, with a no-thrills BX motherboard and an fxp NIC, with a strictly 4.2-Release installation) the rc.diskless2 must be wrong (I've not yet checked with -Stable), as it tries to chmod, chgrp and find

What is the latest "known-good" PXE build ?

Hello, I'm trying to use the pxeboot loader from 4.2-RELEASE, to diskless boot some rack-mount PCs. Using documentation from Alfred Perlstein and Mike Smith, I've configured a DHCP server and a tftp server, and I'm still having problems with at least one machine not being able to start each ti

Re: How to send packets to another interface on the same machine

e recently built a similar test bench, but for latency accuracies in the order of 1 ms (instead of some usecs), using ntp to synchronize the machines. This way, I could measure the the travelling time of packets down to a 1 ms accuracy (from one PC to another, both being synchronized to the same NTP
