   :realtek: の NICが悪く言われる要因の一つと思われるこの RTL8139 ドライバソース中のコメント

   "The RealTek 8139 PCI NIC redefines the meaning of 'low end.' This is probably the worst PCI ethernet controller ever made, with the possible exception of the FEAST chip made by SMC. The 8139 supports bus-master DMA, but it has a terrible interface that nullifies any performance gains that bus-master DMA usually offers."
