NAME

       lat_fcntl - fcntl file locking benchmark

SYNOPSIS

       lat_ctx [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ]

DESCRIPTION

       lat_fcntl  is  a  client/server  program that measures file locking latencies.  The benchmark alternately
       locks and unlocks files so that only one of the client or server is running at a time, similar  to  ``hot
       potato'' message passing benchmarks.  No other work is done in the processes.

ACKNOWLEDGEMENT

       Funding for the development of this tool was provided by Sun Microsystems Computer Corporation.
