 866                  *
 867                  * There was considerable discussion in late July, 2000 regarding
 868                  * slowing down pg_dump when backing up large tables. Users with
 869                  * both slow & fast (muti-processor) machines experienced
 870                  * performance degradation when doing a backup.
 871                  *
 872                  * Initial attempts based on sleeping for a number of ms for each ms
 873                  * of work were deemed too complex, then a simple 'sleep in each
 874                  * loop' implementation was suggested. The latter failed because
 875                  * the loop was too tight. Finally, the following was implemented:
 876                  *
 877                  * If throttle is non-zero, then See how long since the last sleep.
 878                  * Work out how long to sleep (based on ratio). If sleep is more
 879                  * than 100ms, then sleep reset timer EndIf EndIf
 880                  *
 881                  * where the throttle value was the number of ms to sleep per ms of
 882                  * work. The calculation was done in each loop.
 883                  *
 884                  * Most of the hard work is done in the backend, and this solution
 885                  * still did not work particularly well: on slow machines, the
 886                  * ratio was 50:1, and on medium paced machines, 1:1, and on fast
 887                  * multi-processor machines, it had little or no effect, for
 888                  * reasons that were unclear.
 889                  *
 890                  * Further discussion ensued, and the proposal was dropped.
 891                  *
 892                  * For those people who want this feature, it can be implemented
 893                  * using gettimeofday in each loop, calculating the time since
 894                  * last sleep, multiplying that by the sleep ratio, then if the
 895                  * result is more than a preset 'minimum sleep time' (say 100ms),
 896                  * call the 'select' function to sleep for a subsecond period ie.
 897                  *
 898                  * select(0, NULL, NULL, NULL, &tvi);
 899                  *
 900                  * This will return after the interval specified in the structure
 901                  * tvi. Finally, call gettimeofday again to save the 'last sleep
