slow internet - 7.0 release

[Mitja]

Hi!

I started with GreeBSD 7.0 beta3, than RC1 and now I am running Release. 
Everything works great except Internet (I didn't have problem with beta and 
RC). It is slow.
I have standalone comp[uter and as desktop I use KDE. As a browser I prefer 
Konqueror which is very sloqw on many sites (jpgmag.com for example and many 
more) and Firefox which is a little faster.
ifconfig shows:
sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=b<RXCSUM,TXCSUM,VLAN_MTU>
        ether 00:0e:a6:2d:db:82
        inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
rl0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8<VLAN_MTU>
        ether 00:40:05:39:03:de
        media: Ethernet autoselect
        status: no carrier
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> metric 0 mtu 
1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4
        inet6 ::1 prefixlen 128
        inet 127.0.0.1 netmask 0xff000000
pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33204

In the rc.conf I have:

hostname="blabla.com"
ifconfig_sk0="DHCP"
syslogd_flags="-ss"
clear_tmp_enable="YES"
log_in_vain="1"
tcp_drop_synfin="YES"
icmp_drop_redirect="YES"
icmp_log_redirect="YES"
ntpdate_enable="YES"
ntpdate_flags="ntp1.cs.wisc.edu"
linux_enable="YES"
pf_enable="YES"
pf_rules="/etc/pf.conf"
pf_flags=""
pflog_enable="YES"
pflog_logfile="/var/log/pflog"
pflog_flags=""
update_motd="NO"
saver="blank"

And my pf.conf looks like:

# Macros
ext_if="sk0"

# Optimization
set optimization normal
set block-policy drop
set loginterface $ext_if
set skip on lo0

# NOrmalization
scrub in all

# Filtering
antispoof quick for $ext_if

# Closed from outside
block in log quick on $ext_if all label "inblock"

# Open to out
pass out on $ext_if inet proto tcp all flags S/SA modulate state
pass out on $ext_if inet proto udp all keep state

# ping out
pass out on $ext_if inet proto icmp all icmp-type 8 code 0 keep state

If I ping a jpgmag.com sites there are no errors and response is fast.

Thanks in advance.
