■
Adaptive —takes all available information into account when selecting a site.
This setting is a reasonable default.
■
Site Load —the current load at each site is weighted more heavily than other
criteria.
■
Site Weight— the user-defined static weight for each site is weighted more
heavily than other criteria.
5. Specify the Load Balancing Responsiveness. This value controls how aggressively
Equalizer adjusts the site’s dynamic weights. There are five responsiveness settings:
Slowest, Slow, Medium, Fast, and Fastest. The faster settings allow Equalizer to adjust
its load balancing criteria more frequently and permit a greater variance in the relative
weights assigned to sites. A slow setting causes site measurements to be averaged over
a longer period of time before they are applied to the cluster-wide load balancing and
tend to ignore spikes in cluster measurements caused by intermittent network glitches.
6. Click the Set button.
