NAME

       milli, micro, nano, mb, kb - the lmbench reporting subsystem

SYNOPSIS

       #include ``lmbench.h''

       void milli(char *s, uint64 n)

       void micro(char *s, uint64 n)

       void nano(char *s, uint64 n)

       void mb(uint64 bytes)

       void kb(uint64 bytes)

DESCRIPTION

       Creating  benchmarks  using  the  lmbench  timing harness is easy.  Since it is so easy to
       measure performance using lmbench, it is possible to quickly answer questions  that  arise
       during system design, development, or tuning.  For example, image processing

       There  are  two  attributes  that are critical for performance, latency and bandwidth, and
       lmbench's timing harness makes it easy to  measure  and  report  results  for  both.   The
       measurement  interface,  benchmp  is  the same, but the reporting functions are different.
       Latency is usually important for frequently executed operations, and bandwidth is  usually
       important when moving large chunks of data.

       void milli(char *s, uint64 n)
              print  out  the time per operation in milli-seconds.  n is the number of operations
              during the timing interval, which is passed as a parameter because  each  loop_body
              can contain several operations.

       void micro(char *s, uint64 n)
              print the time per opertaion in micro-seconds.

       void nano(char *s, uint64 n)
              print the time per operation in nano-seconds.

       void mb(uint64 bytes)
              print the bandwidth in megabytes per second.

       void kb(uint64 bytes)
              print the bandwidth in kilobytes per second.

FUTURES

       Development of lmbench is continuing.
