My pci performances sucks! i can't understand why...
I tried everything change all hardware (mb, nic)
The pc is a 440Bx board, 256Mb, Celeron 450, ultrastard 10k disk (29160 card):

/dev/sda:
Timing cached reads: 480 MB in 2.01 seconds = 238.25 MB/sec
Timing buffered disk reads: 104 MB in 3.03 seconds = 34.35 MB/sec

Hd speed is ok, with ttcp i get full bandwidth, but if i make a file transfert (inside the same hd) or a network one, throughput is ~5 Mb/s !!!
In win i get 10Mb/s of network transfer and more in filesystem one.
it seams like pci performances sucks... but why? is there any bug or is my fault?
i used 2.6.5, 2.6.11 (and mm), 2.6.12 (and mm)

Below bonnie's results (ext3) ( look at per Char I/O !!! ) :
