Hi,
I've stated a (network / kernel) problem and cannot find how to solve it. Please could you help me.
Many thanks for your help in advance.
:Claudio
Problem:
Only a few K bytes/sec get transfered by a Thin-ethernet. Test were run using the program 'spray'. Even by spraying on localhost the transfer rate can be as low as 19K bytes/sec.
Constellation:
Just two hosts are connected.
I--------> alpha 10.10.10.10 FreeBSD 2.2.1
I
I
I--------> gamma 10.10.10.11 FreeBSD 2.2.2
Facts:
The problem persists independantly whether the tests are driven using Novell 2000 ethernet cards as well as 3Com 3c509 cards. The kernels are compiled for both driver cards at the moment. But even when compiled for only one card type the behaviour is the same.
Whether NIS is enable or not does neither influence the bad behaviour.
Configurations:
1) alpha% cat sysconfig
2) alpha% cat hosts
3) alpha% dmesg
4) gamma% cat rc.conf
5) gamma% cat hosts
6) gamma% dmesg
Tests:
7) alpha% spray localhost
8) alpha% spray alpha
9) alpha% spray gamma
10) gamma% spray localhost
11) gamma% spray gamma
12) gamma% spray alpha

# The following choices are BAD:
# The IRQ's on COM-ports (SIO devices), the IRQ used by a "classic"
# IDE disk or cdrom (Intelligent controllers seem to be OK), and
# the IRQ on the system clock.
#
# Experiment with the rest. The best interrupts are the ones that
# happen fairly irregularly, and never occur in very high-speed bursts.
#
# You'll have it right when you have a good supply of numbers from
# /dev/random, and no problems on your system, like slowdowns,
# Sluggish net/disk activity, perhaps even errors.
# For example - if you have a sound blaster on IRQ5, an ethernet card
# on IRQ10 and a SCSI controller on IRQ11 (eg ADAPTEC 1542) you might
# try this:
