FreeBSD 6.3 Dual Quad Core Xeon [EMAIL PROTECTED] 16GB RAM 3Ware 9650SE-ML / 256MB cache 14 Seagate 750GB/7200RPM/ST375033ONS SATA drives
We have an application that is streaming data to disk at the maximum rate the controller can sustain. The controller should be able to develop something on the order of 600MB/s but we're only getting 450MB/s. The application writes about 50GB into a file, closes the file, and then starts another file. I've set all of the recommended settings from 3ware. I have tried various settings for vfs.hirunningspace - various settings include everything from 5MB to the cache size of the card (256MB). Does anyone know if there is some file system performance limit? Thanks
