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
