Subject: Looking for Linux XFS file system performance tuning tips for LSI 9271-8i + 8 SSD's RAID0
Date: Sun, 03 Feb 2013 13:36:48 -0700 [thread overview]
Message-ID: <courier.510ECA60.00003A99@softhome.net> (raw)
I am working with hardware RAID0 using LSI 9271-8i + 8 SSD's. I am using
CentOS 6.3 on a Supermicro X9SAE-V motherboard with Intel Xeon E3-1275V2 CPU
and 32GB 1600 MHz ECC RAM. My application is fast sensor data store and
forward with UDP based file transfer using multiple 10GbE interfaces. So I
do not have any concurrent loading, I am mainly interested in optimizing
sequential read/write performance.
Raw performance as measured by Gnome Disk Utility is around 4GB/s sustained
read/write. With XFS buffer IO, my sequential writes max out at about 2.5
GB/s. With Direct IO, the sequential writes are around 3.5 GB/s but I
noticed a drop-off in sequential reads for smaller record sizes. I am
trying to get the XFS sequential read/writes as close to 4 GB/s as possible.
I have documented all of the various mkfs.xfs options I have tried, fstab
mount options, iozone results, etc. in this forum thread:

Please let me know if you have any suggestions.
