I have a SQL2K enterprise box with performance issues. It is composed of a single RAID 5 with 6 disks, identified as the "D" drive. It has 8Gb RAM, a fixed memory setting of 6079, with AWE enabled and 3GB/PAE set in boot.ini. Once the 8GB was added and AWE enabled, performance increased by about 50%, but performance is still unacceptable. I have posted Memory and Physical Disk counters on this website and was told that both are acceptable. While I have not posted the CPU counters on this website, I am fairly confident that they are acceptable too. I have run Profiler and it does appear some queries could benefit from some optimization. However, my instinct is that due to the across board, unacceptable performance, it goes beyond query tuning, though I am sure that would be of some help. In looking at the Log file and Data file placements, both the Log and Data files are place on the RAID 5, "D" drive. From the Physical Disk counters (as posted on this website) it appears I have 1% Read Time versus 70% Write Time. My recommendation would be: 1. Place the Log files on RAID 1 2. Obtain another RAID 5, separating the tables and indexes into separate filegroups, placing tables on one RAID 5 and indexes on the other RAID 5. Would you concur with the above as a reasonable recommendation?
