Hi, I am having performance issues with my file server running SUSE Linux 10.0 (64bit on an Athlon64). The systems data disks consist of 4 200GB Samsung SATA drives on separate onboard ports on the motherboard which are then configured together as md0 using Linux software raid5 (giving 600GB usable). This is then added to a LVM volume group and has several logiccal volumes and filesystems created on it Bonnie output (using a 2GB file on one of the LVM filesystems housed on md0) is as follows: belgarath:/data02 # bonnie -s 2000 Bonnie 1.4: File './Bonnie.8151', size: 2097152000, volumes: 1 Writing with putc()... done: 46912 kB/s 75.1 %CPU Rewriting... done: 19625 kB/s 12.4 %CPU Writing intelligently... done: 47675 kB/s 25.8 %CPU Reading with getc()... done: 27555 kB/s 51.3 %CPU Reading intelligently... done: 46055 kB/s 15.3 %CPU Seeker 1...Seeker 2...Seeker 3...start 'em...done...done...done... ---Sequential Output (nosync)--- ---Sequential Input-- --Rnd Seek- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --04k (03)- Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU belgar 1*2000 46912 75.1 47675 25.8 19625 12.4 27555 51.3 46055 15.3 265.3 2.3 The system is connected to a Netgear gigabit switch using cat6 or cat5e (tried both) via a PCI Netgear GA302T Gigabit card. Ethtool reports that the card is connected at 1000FD and no network errors are shown. I think that the Netgear card uses the tg3 driver The Windows box is connected to the same gigabit switch using a 3com 3C2000 gigabit card and has a single local SATAII disk. The network card reports is is connected at 1000FD. Accessing the system via samba from a Windows XP box seems quite slow as does accessing it via SFTP, (a sustained SFTP transfer using Filezilla peaked at 310kb/s .... a 670MB iso image has just taken 35+ minutes to transfer across between them). Tests were performed when both the systems and the network were quiet and are reproducable both using other systems and copy files from non-raided disks on the Linux box. Has anyone got any suggestions on where the bottleneck may be and what I could possibly do to improve matters. From the Bonnie figures I am guessing the issue is more likely to lie on the networking side rather than the disk side?
