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).
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
Exit Status
On success, returns zero. On failure, returns non-zero.
