I'd guess this dd+nc method isn't showing his peak throughput potential due to the way dd does buffering. Testing with FTP may, say a 100MB file. TCP encapsulation and ethernet framing overhead on 100FDX ethernet aren't anywhere near 20% of the line bit rate. I'm showing throughput at 92% of line bit rate with FTP transfers, with 100FDX. Regardless, with any test, 10MB/s isn't bad by any means for fast ethernet. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
