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.
