Hi list, i'm developing an application (in C) which needs to write about 1Gbit/s (125Mb/s) to a disk array attached via U320 SCSI. It runs on Dual Core 2 Xeons @2Ghz utilizing kernel 2.6.22.7.
I buffer the data in (currently 4) 400Mb buffers and use write(2) in a dedicated thread to write them to the raw disk (no fs). The write(2) performance is not good enough, the writer threads take to much time, and i ask you for ideas, howto to boost the write performance. Maybe mmaping the disk would work? Cheers, -Michael PS. I would like to be cc'd as i usually don't read the list due to high traffic. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
