Sorry for my wrong posting
Hi,
i think the setting of HZ has nothing to do with DEVICE_POLLING at once.
So the Documentation say's DEVICE_POLLING is an Other way to get the
Packets from the Ethernet.
I have setted HZ=2000 on all my machines, equal if the Processor is an PI 200MHz
or an PIII 8

No. Can you observe the broken IP/TCP/UDP checksums?

All, but PC1 with fxp, use polling, with:
options DEVICE_POLLING
options HZ=1000
1000 IMHO seems a bit too heavy. Try something
lower

Hmmm, how do you "find a good balance" ?
Network access speed vs. lost connections.?
Yes. The access times during the top load period and

What is heavy
Hi,
just one experience of mine with Realtek 8139. I was not able to FTP
upgrade Suse 9.2. Data transfer was crashing. After some *research* I
changed the 8139 and problem was solved. The server was on 3c905B.
Cheers,
Vlado.

Ruslan,
Yesterday I discovered that polling of the xl
interface randomly disrupts an ssh-tunnel of mine.
I think there's still a subtle, yet critical problem
