| Ethernet to USB 2.0 is very slow When I send data over ethernet to a drive running on the USB 2.0 its very slow. This is PC to PC over 100baseT wired home LAN to do disk backups. The slowness occurs in the translation from 10baseT100 to the USB 2.0 and the CPU is 100% utilized. Are there cards that offload the CPU processing needed to do this translation? I have a PCI combo card (w/firewire), brand new installed. The following clues narrow the problem down to the USB to ethernet conversion as the problem.: PC to PC over ethernet from installed HD to installed HD is very fast. PC from its own C: drive to the USB 2.0 drive is very fast. but when do PC to PC over ethernet to save data on theh USB 2.0 drive its very very slow...like 5x slower then drive C: to USB 2.0. Any thoughts?      |
