I've been doing some throughput test etc. ans saw that wen 'n transfer large amounts of data (ttcp or ftp) 'n get round about 50% collision rate (according to netstat -i and some mathematics :) ) Is this normal ??? I used a x-over cable and a hub between the two machines, both running 2.2.7 ... one 233 PII and the other 300 PII Although there was such a high rate of collisions the throughput was still +/- 880 to 990 kbytes/sec Thanx Reinier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
