NAME

       chirp_benchmark - do micro-performance tests on a Chirp server

SYNOPSIS

       chirp_benchmark <host[:port]> <file> <loops> <cycles> <bwloops>

DESCRIPTION

       chirp_benchmark  tests a Chirp server's bandwidth and latency for various Remote Procedure
       Calls. The command uses a combination of RPCs that do and do not use I/O bandwidth on  the
       backend  filesystem  to  measure the latency. It also tests the throughput for reading and
       writing to the given filename with various block sizes.

       For    complete    details    with    examples,    see    the    Chirp    User's    Manual
       (http://ccl.cse.nd.edu/software/manuals/chirp.html).

EXIT STATUS

       On success, returns zero.  On failure, returns non-zero.

EXAMPLES

       To test a Chirp server, you may use:

               $ chirp_benchmark host:port foobar 10 10 10
               getpid     1.0000 +/-    0.1414  usec
               write1   496.3200 +/-   41.1547  usec
               write8   640.0400 +/-   23.8790  usec
               read1     41.0400 +/-   91.3210  usec
               read8      0.9200 +/-    0.1789  usec
               stat     530.2400 +/-   14.2425  usec
               open    1048.1200 +/-   15.5097  usec
