Well, these aren't of big interest atm. I posted a question in -current 
regarding horrible ftp transfer rates (fwe and em transfer rates).
He was the only one answering and regrettably confirming my experience.
First, tell me why a 866MHz PII machine is full loaded for transfering 22MB/s 
(over em0 and ftp, disks can do more that 50MB/s, no switch, just direct 
connect, no packet loss/mutilation.......)?

There is such a big performance hole that it's really uninteresting if one 
runs syslogd on one machine and not on the other...
