Hello,
after a recent upgrade from 3-Stable to 4-Stable I have noticed that
the network speed of my NetBSD Box has declined dramatically, to
the point were even ssh is almost unusable and most connections time
out at some point, even inside my local network.
The box in question is connected to my home network over a 1Gbit Lan,
which in turn is connected to the outside world with 16Mbit DSL. It
runs on 4-Stable (i386) with the GENERIC.MP Kernel, the NIC gets
correctly identified as an Intel Card:
[root@datenschleuder:~ ] dmesg | grep wm
<Sun 08/05> wm0 at pci0 dev 3 function 0: Intel i82541PI 1000BASE-T
Ethernet, rev. 5 wm0: interrupting at ioapic1 pin 6 (irq 11) wm0:
32-bit 33MHz PCI bus wm0: 64 word (6 address bits) MicroWire EEPROM
wm0: Ethernet address 00:0e:0c:c3:11:12
igphy0 at wm0 phy 1: Intel IGP01E1000 Gigabit PHY, rev. 0
These are the average times I get when pinging the Box from another
Machine inside the local Network:
mfk@sysiphus:~$ ping -c 3 datenschleuder
PING datenschleuder.pulp-friction.local (192.168.0.100) 56(84) bytes of
data.
[...]
--- datenschleuder.pulp-friction.local ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2011ms
rtt min/avg/max/mdev = 4071.135/5075.396/6082.963/821.330 ms, pipe 3
For a comparison, the average ping time to google.de is about 29ms on
my Desktop (Ubuntu), establishing a ssh-session to the netbsd machine
takes about 30 seconds to 1 minute (inside the local network)
ifconfig looks normal to me:

/var/log/messages and netstat don't show anything out of the ordinary
either.
This is all pretty vague, but at the moment I don't have any idea as
where to look or what to try next, except somehow going back to
3-Stable.
So what else is there to try? I can provide additional data (like a full
dmesg) if there's any need.
Thanks in advance!
