Hi,
I upgraded a few days ago from 3.4-STABLE to 4.0-CURRENT, and without
really any change in configuration, anything tcp/ip is much slower. Just a
standard "ping localhost" has gone from ~0.155ms to ~0.195ms. Averages for
"ping -f localhost" have gone from ~0.100ms to ~0.160ms. FTP over my lan
"vr0" has slipped from 7.7MB/s down to 4.8MB/s (!).
I've got hardly anything running on my machine (natd, samba, postfix,
pppd). 'top' shows 99-100% idle pretty much all the time. Load averages are
all 0.00. CPU usage goes upto 100% during the ftp transfer.
Here's the output of my dmesg:

Here's the first 4 relevant ipfw rules:
00050 allow icmp from any to any
00100 divert 8668 ip from 192.168.1.2 to any out xmit ppp0
00100 divert 8668 ip from any to any in recv ppp0
00200 allow tcp from any to any established
I used the same config for 3.4. The only difference is in using ata instead
of wd for my hard drives. And the new miibus controller for my ethernet card.
I would've thought that 4.0 would be faster. Is it supposed to be? Does
anybody know of any major difference in 4.0 that would give me these speed
decreases? And possibly how to fix them?
Your help is much appreciated.
Cheers
