To work at top speed, updates to the weights for the servers
are only made if the weights have changed significantly. Constantly
updating the weights when there is little or no change in the server
status could create unnecessary overhead.
About this task
When the percentage weight change for the total weight
for all servers on a port is greater than the sensitivity threshold,
the manager updates the weights used by the executor to distribute
connections. Consider, for example, that the total weight changes
from 100 to 105. The change is 5%. With the default sensitivity threshold
of 5, the manager will not update the weights used by the executor,
because the percentage change is not above the threshold. If, however,
the total weight changes from 100 to 106, the manager will update
the weights.
Note: In most cases, you will not need to change this
value.
