Hello,
(Still trying to optimize my VIA C3 :-)
When I run `find /mnt/nfs -type f -name "*whatever*"` from my C3, I see
Interrupts going from ~200 to ~8000/10000.

Since the `find` stops, Interrupts go down back to 200 in 2 seconds.
If I do the same thing on my laptop (Core2Duo), Interrupts go from ~270 to
~700/900.
Is ~10K Interrupts expectable or does this imply a
hardware/configuration issue ? If so, what would be the issue ?
The network driver ?
==========
rtk0 at pci0 dev 8 function 0: Realtek 8139 10/100BaseTX (rev. 0x10)
rtk0: interrupting at irq 11
rtk0: Ethernet address 00:30:18:4a:2e:88
rlphy0 at rtk0 phy 7: Realtek internal PHY
==========
The NFS mount options ?
==========
guarana:/home on /amd/guarana/root/home type nfs (nosuid, nodev, fsid:
0xb03/0x70b, reads: sync 0 async 0, writes: sync 0 async 0)
==========
The C3 is wired-connected to the NFS server (100baseTX full-duplex).
The Core2Duo is wireless-connected to the NFS server (OFDM54 mode 11g).
Any idea ?
TIA,
Jo
