Performance Advice

As discussed in the SAP Portal InfoBrief, the prefetcher setting in the BIOS has a major influence on SAP performance. On ABAP, switching OFF the prefetcher (in a benchmark scenario) increased the system throughput (in Dialogsteps per second) by about 8%, even more could be observed inJAVAin JAVA stack based SAP software. To switch off the prefetcher (as of an R900's example):

1. Reboot your PowerEdge server
2. Enter your system BIOS by pressing F2
3. Chose CPU Information -> Adjacent Cache Line Prefetch
4. Set this option to "disabled"

Note: This option may also be called "Sequential Memory Access", depending on your server.
