Hi

Thread is quite old for reply but maybe this will help

our setup : - we set blockdev of RAID devices to 4096 - RAID stripe to 256K - scheduler must be set to "deadline" (on Linux see /sys/block/sda/queue/scheduler) - xfs used here with these options : noatime,nobarrier - worker_processes should be equals your number of cores, we have 16 - disable logging - sendfile_max_chunk 512k; - sendfile off; - tcp_nopush on; - tcp_nodelay on; - output_buffers 1 1m; - keepalive_timeout 0;

With this setup we can do 1.7 GBits/s traffic. We are serving bigger files so these wont be ideal for your situation but may be helpful. We have 28TB of data per server.

FYI we do 350 mbytes/s on Treeware/Adaptec SATA RAID. You may try bonnie ++ on this box to see how it can do on plain disk access.

have a nice day
