6945/163914 (4.2%) packet loss, when transfering 200MB data,
the system is 80% idle

I think you may not get correct test result when other system activity
such as disk I/Os is in progress. Just stick to check pure network
performance. For ftp, you can request "/dev/zero" from ftp server
and save it as "/dev/null" on client in order to avoid disk I/Os.
