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?
