config load-balance connection-pool

Use this command to configure connection pool settings.

A connection pool enables Layer 7 load balancing virtual servers to “reuse” existing TCP connections. Using a connection pool can reduce the impact of TCP overhead on web server and application performance.

Before you begin:

• You must have read-write permission for load balancing feature settings.

After you have created a connection pool configuration, you can specify it in a virtual server configuration.

Note: The feature is not supported for profiles with the Source Address option enabled.

Syntax

config load-balance connection-pool

edit <name>

set age <integer>

set reuse <integer>

set size <integer>

set timeout <integer>

next

end

age	Maximum duration of a connection in seconds. The recommended value is 3000.
reuse	Maximum number of times that the virtual server can reuse the connection. The recommended value is 2000.
size	Maximum number of connections in the connection pool. The recommended value is 0, which specifies that there is no limit on the connection size.
timeout	Maximum number of seconds a connection can be idle before the system deletes it. The recommended value is 30.

Predefined connection-pool

config load-balance connection-pool

edit "LB_CONNECTION_POOL_DEFAULT"

set size 10000

set age 86400

set reuse 10000

set timeout 50

next

end

Example

FortiADC-VM # config load-balance connection-pool

FortiADC-VM (connection-pool) # edit lb-connection-pool

Add new entry 'lb-connection-pool' for node 1698

FortiADC-VM (lb-connec~i) # get

size : 10000

age : 86400

reuse : 10000

timeout : 50

FortiADC-VM (lb-connec~i) # set age 3000

FortiADC-VM (lb-connec~i) # set reuse 2000

FortiADC-VM (lb-connec~i) # set size 0

FortiADC-VM (lb-connec~i) # set timeout 30

FortiADC-VM (lb-connec~i) # get

size : 0

age : 3000

reuse : 2000

timeout : 30

FortiADC-VM (example-connec~i) # end
