Interestingly: HZ=1000 is apparently a problem with

What could cause that difference? Could a difference
in buffer size on the LAN card cause this?
Yes. GigE cards tend to

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

Same problem.

In Device Polled systems, the NIC does not generate any interrupt at
all. Instead whenever the packets arrive at a Network interface, they
are captured and put into a queue. The kernel scheduler checks the quese
at regular intervals and processes the packets which are waiting.

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

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

Argh, just found out that it is not the polling.
Even without the polling, the ssh-tunnel connection
gets disrupted, although not as frequent as with
the polling. Possibly, the polling makes the problem
more visible, but it not the culprit.

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

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.
