PF enable = low upload

Hi,

FreeBSD 9.1 64bit is installed as guest on XenServer 6.1.0. Everything is working fine, until I enable PF. When PF is enabled:
Code: 
[17:41:01] [/root]#  pfctl -e
No ALTQ support in kernel
ALTQ related functions disabled
pf enabled
Upload is around 6-8Kb/s.

When PF is disabled, upload is normal, max 100Mb/s:
Code: 
[17:41:03] [/root]#  uname -a
FreeBSD some.host 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r249920: Fri Apr 26 07:26:21 UTC 2013     root@some_host:/usr/obj/usr/src/sys/XENHVM  amd64
Code: 
cat /etc/rc.conf
hostname="some_host"
ifconfig_xn0=" inet my_IP netmask 255.255.255.0"
defaultrouter="my_router"
sshd_enable="YES"
# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="NO"
syslogd_flags="-ss -4"
clear_tmp_enable="YES"
ezjail_enable="YES"
pf_enable="YES"
pf_rules="/etc/pf.conf"
pf.conf and sysctl.conf are empty for tests. I have no idea why upload is so low after enable "empty" PF.

Thanks for help.
 
OK, problem is with some XENHVM kernel options. On GENERIC everything is fine.

XENHVM options:
Code: 
options         NO_ADAPTIVE_MUTEXES
options         NO_ADAPTIVE_RWLOCKS
options         NO_ADAPTIVE_SX

# Xen HVM support
options         XENHVM
device          xenpci


Someone have any idea? Can I # something?
