/*  This program does a number of iterations of v f m t s
 *  By Michael Black W9MDB
 *  This simulates what WSJT-X and JTDX do
 *  Used in testing caching effects that have been added
 *  Original performance against dummy device with 20ms delays showed
 *  about 50 calls/sec to get frequency.  After caching was added can
 *  do about 37,000 calls/sec or about 740 times faster.
 *  To compile:
 *      gcc -I../src -I../include -g -o cachetest cachetest.c -lhamlib
 *  To test dummy device cache effect:
 *      dummy without any cache -- 12 iterations per second
 *      ./cachetest 1 "" 0 12 0
 *      Elapsed:Elapsed 1.004sec
 *
 *      dummy with 500ms cache (default value) -- 12 iterations in 0.071sec
 *      ./cachetest 1 "" 0 12 500
 *      Elapsed 0.071sec
 *
 *      dummy with 5700 iterations in less than 1 second with 500ms cache
 *      ./cachetest 1 "" 0 5700 500
 *      Elapsed 0.872sec
 *
 *      ic-706mkiig  -- no cache
 *      ./cachetest 3011 /dev/ttyUSB0 19200 12 0
 *      Elapsed 1.182sec
 *
 *      ic-706mkiig  -- 500ms cache
 *      ./cachetest 3011 /dev/ttyUSB0 19200 12 500
 *      Elapsed 0.13sec
