[1] In contrast, when using Linux LVM as a volume manager, iostat does display volume information individually, because each logical volume has its own device mapper (dm ...
It is a multi-purpose benchmark that features tests for CPU, memory, I/O, and database performance testing. [3] It is a basic command line utility that offers a direct way to benchmark computer hardware.

For each computer system, the following quantities are reported: [2] R max: the performance in GFLOPS for the largest problem run on a machine. N max: the size of the largest problem run on a machine. N 1/2: the size where half the Rmax execution rate is achieved. R peak: the theoretical peak performance GFLOPS for the machine.

This is done by defining a series of state-components, each with a size and offset within a given save area, and each corresponding to a subset of the state needed for one CPU extension or another. The EAX=0Dh CPUID leaf is used to provide information about which state-components the CPU supports and what their sizes/offsets are, so that the OS ...
