RB> You've been told the following, *repeatedly*:

RB> Your hardware is not capable of keeping up with the level of network traffic
RB> it is being subjected to.

RB> Reaaltek cards and the 're' device driver are a *BAD*CHOICE* for systems with
RB> heavy network traffic.  They're merely 'medium lousy' on a lightly-loaded
RB> system, but you don't notice the problems under light loads.

RB> You have two choices:
RB>   1) "live with" the crappy performance
RB>   2) get a better quality network card.
