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¶
