[Samba] my file transfers are incredibly slow

[David]

My problem is there I download and archive my work to the freebsd server via
samba.  When I'm transfering files from the windows -> freebsd I will get
anywhere between 20-100kB/s and from freebsd -> windows I will get a few
mbps.  I'm getting no where near a full 100mbps and both ethernet cards are
set for 100mbps full duplex working great.  I've tried increasing buffer
sizes on the network to over 65535 bytes and nothing seems to work.

(xl0 = LAN, xl1 = internet)
I've included some information and I know it's still a general question but
I'm hoping someone can work with me on this issue.  I'd really like to keep
samba but I need it to perform.  I need to be able to get atleast a 35%
efficiency rate. Thanks in advance.

Here is some info from top as I was transfering a large file:
