I have a question about the PCI Bursting and overall processing speed on a dual Xeon box; but first I have to give a slight bit of background, (all of it relevant to the question) I'll try and keep it short.
what do you mean by "PCI Bursting" ?? are you using DMA (PCI card Mem
Write Multiple) or MMIO read (CPU Mem Read Line) ?
anyway on my system, 2 CPU Xeon 2.6GHz GC-LE + a custom PCI-X 100MHz
card, I get
- 440.755 MByte/s, only 1 process
- 424.683 MByte/s, the process below running:
sh -c 'while true ; do echo miao ; done' > /dev/null
it's:
Linux xeino 2.4.22-1.2199.nptlsmp #1 SMP Wed Aug 4 11:48:29 EDT 2004
i686 i686 i386 GNU/Linux
what is your kernel version?
