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.
