[FUGSPBR] Rede lenta, sera a rtl8139 ??? ou outro setting ?

[craker maudoso]

Ola,

Tenho um free4.4 com natd para uma rede interna,
no servidor sao duas placas rtl8139.

A transferencia de arquivos dos mircros clientes
para o servidor(ip por DHCP) fica lenta, nao passa de 150 kbits/s.
O interessante é que a transferencia fica lenta somente
entre as maquinas clientes e o servidor, para
transferencias de fora da rede, fica rapido.

No link abaixo tem um caso sobre lentidao na 8139:

http://profile.sh/syswiki/index.php?Why%20do%20I%20have%20Very%20low%20transfer%20speeds%20with%20Realtek%208139%3F

Estou enviando abaixo o rc.conf, rc.ipfw e ifconfig, se alguem
enxergar algum erro que justifique essa lentidao nas transferencias
(ftp, www) entre o servidor e as maquinas da rede interna, eu agradeco
muitissimo.
