Hi,
Just to be sure that you have latency on your server you can use this irule, it will permit you to target where latency come from:
when HTTP_REQUEST {
set http_request_time [clock clicks -milliseconds]
}
when HTTP_REQUEST_RELEASE {
set http_request_time_release [clock clicks -milliseconds]
}
when HTTP_RESPONSE {
set http_response_time [ clock clicks -milliseconds ]
}
when HTTP_RESPONSE_RELEASE {
set http_response_time_release [ clock clicks -milliseconds ]
log local0.info "[virtual] Time to match: request: $http_request_time - request_release: $http_request_time_release "
log local0.info "[virtual] Time to match: response: $http_response_time - request_release: $http_response_time_release"
log local0.info "[virtual] Time to response (request F5 process) = [expr $http_request_time_release - $http_request_time]"
log local0.info "[virtual] Time to response (response F5 process) = [expr $http_response_time_release - $http_response_time]"
}
