DP performance

2005-11-28 Thread Danial Thom
It seems most of the banter for the past few months is userland related. What is the state of the kernel in terms of DP/MP kernel performance? Has any work been done or is DFLY still in the cleaning up stages? I'm still desparately seeking a good reason to move to Dual-core processors DT

If we are talking about maxing out a machine in the packet routing role, then there are two major issue sthat have to be considered: * Bus bandwidth. e.g. PCI, PCIX, PCIE, etc etc etc. A standard PCI bus is limited to ~120 MBytes/sec, not enough for even a single GiGE
