Hello, Freebsd-geom. Is here any good I/O benchmark? What do I mean by `good': (1) Multiprocess workloads with different workloads per processe (thread) (a) Sequential R or W. (b) Random R and W with configurable R:W ratio. (c) Configurable min/max/avg distance seek in random workloads. (2) All above with configurable block size. (3) All of above with configurable I/O queue depth. --=20 // Black Lion AKA Lev Serebryakov <lev@serebryakov.spb.ru>
