Load Balancing Policy
Description
adaptive
adaptive
load balancing distributes the load according to the
following performance indicators for each server.
Server response time
is the length of time for the
server to begin sending reply packets after Equalizer
sends a request.
Active connection count
shows the number of
connections currently active on the server.
Server agent value
is the value returned by the
server agent daemon (if any) running on the server.
fastest response load balancing
fastest response load balancing
dispatches the highest
percentage of requests to the server with the shortest response
time. Equalizer does this carefully: if Equalizer sends too many
requests to a server, the result can be an overloaded server with
slower response time. The fastest response policy optimizes the
cluster-wide response time. The fastest response policy also checks
the number of active connections and server agent values (if
configured); but both of these have less of an influence than they do
under the adaptive load balancing policy. For example, if a server’s
active connection count and server agent values are high, Equalizer
might not dispatch new requests to that server even if that server’s
response time is the fastest in the cluster.
least connections load balancing
dispatches
least connections load balancing dispatches
the highest
percentage of requests to the server with the least number of active
connections. In the same way as Fastest Response, Equalizer tries
to avoid overloading the server so it checks the server’s response
time and server agent value. Least Connections optimizes the
balance of connections to server pool in the cluster.
server agent load balancing dispatches
server agent load balancing dispatches
the highest percentage
of requests to the server with the lowest server agent value. In a
similar way to Fastest Response, Equalizer tries to avoid overloading
the server by checking the number of connections and response
time. This method only works if server agents are running on the
server pool in the cluster.
