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

[Marcelo Pereira]

Cara, tive o mesmo problema
com essa placa. O problema estah
nela mesmo. Troquei por uma 3c509
e ficou bala. Antes alem do trafego
estar por volta de 170kbits/s, o mesmo
para va por ateh 15 segundos e depois
retornava. Troque-a o
+ rapido possivel. Ahh, o problema
naum estah no FreeBSD+rtl8139,
isso acontece com qualquer SO. Aparente-
mente o problema estah na incompatibilidade
dessa placa com alguns HUBs e Switches.
