lperfex: a Hardware Performance Monitor for Linux/IA32 Systems
http://www.osc.edu/~troy/lperfex/ perfex is a utility which accesses the hardware performance counters on Intel P6-based Linux systems to measure performance characteristics of other programs. It functions similarly to the Cray UNICOS hpm and the SGI IRIX perfex utilities, in that you can use lperfex to measure performance metrics like megaflops on existing applications without having to recompile or instrument them. lperfex : a Hardware Performance Monitor for Linux/IA32 Systems now available; this is a MAJOR update and requires a a different kernel patch than previous versions. See the archives for older versions. As part of OSC's work with Linux/IA32-based clusters, I have developed a small utility,See website for more details...

SGI Runs TPC-H Benchmark on Linux on a SGI 1450 server with four nodes, each of which has four processors, running a 2.4.3 kernel and IBM's DB2 database. The resulting performance set a new world record for databases.
