그렇게 심도 있는 질문도 아니구요..(심도 있는 질문을 드릴만한 지식도 없습니다..)
iperf 를 이용한 테스트를 해보았는데요...
튜알3 1.4-512MB,7200rpm 80GB IDE 입니다.. Archlinux 이구요...
특별히 리소스를 잡아 먹을만한 데몬은 없습니다..
구동이 되어 있어도 데몬만 떠있지 접속조차 없구요...
바톤 2500+에 1.5GB램에 10000RPM 18GB SCSI 하드입니다..
win xp pro sp2 입니다..
linux <- win 로 테스트를 하면 대략 50Mb/s 대 정도 나옵니다..
그런데 linux -> win 테스트 하면 96Mb/s 대 정도로 나오네요..
CPU의 차이일까요? 어짜피 내부랜의 테스트 이어서 외부 망은 거치지 않았습니다..
cpu의 차이때문에 생긴 속도 저하일런지... 아니면 하드디스크의 문제일런지..
혹 랜카드?
혹시나 필요하실까 dmesg 내용을 첨부합니다.

의문 추가합니다..
하드는 IDE인데 왜 scsi device로 잡히나요?
커널 2.6.20 이 원래 그런가요?
FreeBSD 그냥 사용할껄... 괜히 외도를 하는가 싶군요..흠..
짧은글 일수록 신중하게.
