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.

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
