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.
