Impressive how Matthew Dillon's project jumps forward now. And it is still impressive to see that the picture is still in the right place when it comes to a comparison to Linux. Also, OpenIndiana shows an impressive performance. But this is only one suite of testing. Scientific Linux is supposed to give the best performance for scientifi purposes, i.e. for longhaul calculations, much numerical stuff. It outperforms in a typical server application FreeBSd, were "FreeBSD shoulkd have the power to serve". Is the postgresql benchmark the only way to benchmark? Well, this inspires me to gather together all the benchmarks someone could find. There were lots of compalins about FreeBSD's poor performance with BIND - once a domain of FreeBSD. Network performance seems also to be an issue if it comes to scalability. It would be nice to see what portion of the raw CPU/GPU power the OS (FreeBSD, Linux ...) delivers to scientific applications. I only know some kind of benchmarks, BYTE UNIX benchmark, LINPACK test ... Does someone know a site to look for a couple of benchmarks to test a) memory system b) scalability (apart from pgbench) c) network performance/throughput/network scalability d) portion of CPU performance the system delivers for numerical applications to the user apart from the system's own consumption e) disk I/O performance and scalability it would also be nice to discuss some nice settings and performance tunings for FreeBSD for several scenarios. I guess, starting developing benchmarking test scenarios for several purposes would lead faster to real numbers and non polemic than weird discussions ...
