I'm copying a big chunk of data to a single file on an NFS server (in this case, using ntfsclone to back up a NTFS partition). Both the client and the server are on gigabit ethernet, and both are running FC6. I see the disk LED come on solid for several seconds, then start flickering, then go out for a second or two. If I watch the network switch, it does the opposite: no traffic, then a burst of traffic. Because of this, my total throughput is only about 200Mb/s.
Have you tested your network with ttcp? When I want to move data fast from one machine to another, it use ttcp as well: On the receiver I start: cd /some/place ttcp -l10240 -r | tar xv - Then on the transmitter: cd /some/place tar cf - . | ttcp -l10240 -t receiver The number 10240 is the tar block size, 20x512 Mogens -- Mogens Kjaer, Carlsberg A/S, Computer Department Gamle Carlsberg Vej 10, DK-2500 Valby, Denmark Phone: +45 33 27 53 25, Fax: +45 33 27 47 08 Email: mk@xxxxxx Homepage: http://www.crc.dk
