dbench 4.0-2 (arm64 binary) in ubuntu xenial

 dbench and tbench simulate the load of the netbench "industry
 standard" benchmark used to rate (windows) file servers. Unlike netbench,
 they do not require a lab of Microsoft Windows PCs: dbench produces
 the filesystem load on a netbench run, and tbench produces the
 network load, allowing simpler bottleneck isolation.
 .
 Note that this benchmark is *not* a realistic reflection of normal
 server load.
