|2 disk RAID-0||4 disk RAID-0||6 disk RAID-5||6 disk RAID-10|
All of the tests were performed on a Dell PowerEdge 2950 with 2xQuad Core Xeon,16GB of memory and 6x146Gb SAS drives on a Perc/5 RAID controller, and all filesystems were standard EXT3. The TPCC benchmarks were conducted with a smallish buffer pool (2GB) and a 1GB log file size. The database is approximately 7GB in size (100 warehouses). I wanted to show what performance an I/O bound test would yield. The numbers here show that its possible just to get that added boost without resorting to re-creating the entire database with a different filesystem (like XFS). I will come back to XFS later as it provides the best performance.
