How much performance loss?

Hi there !

I am trying to get FreeBSD properly running on my Soekris net4801, and
for that reason I have compiled a custom kernel that doesnt have
support for the hardware that I do not have.

When booting, the kernel gives me the following complaint:

FreeBSD 5.4-RELEASE-p6 #2: Sat Aug  6 11:56:49 CEST 2005
    nivo at imhotep.yuckfou.org:/usr/src/sys/i386/compile/NET4801
WARNING: debug.mpsafenet forced to 0 as ipsec requires Giant
WARNING: MPSAFE network stack disabled, expect reduced performance.

So, I expect a little perfomance loss. When, however, I try to use the
device as an access-point (WLAN 802.11g/WEP-128 in bridging mode) I
cannot seem to get more than 10kbit/s performance over the bridged
wlan interface.

Is this the kind of performance-loss I am being warned about? I
seriously hope not :-)

If it is, how can I keep the full wireless speeds, while still using
IPsec?

Thanks a bunch,

Nils.
