Hi,
We have a deployment of Geoserver 2.1 on weblogic and control flow module
extension is not installed on it. Now the web client is sending quite a high
number of WMS requests to the Geoserver. In the logs I see the messages as
pasted below with the requests starting with Request: getServiceInfo. The
client is sending all requests in parallel but there is a big time gap(~1 min)
between the first and the last "Request: getServiceInfo" in the log. As a
result the impage rendering on the client is taking over one minute. I would
like to know:
1. The time mentioned against each Request: getServiceInfo message is the
timestamp when GeoServer is receiving the request or starting to processing
them?
2. By default, can GeoServer receive and hold back the requests in a
queue/memory and then slowly process them? We are seeing five Request:
getServiceInfo messages at a time. Which parameter is controlling that five
requests will be processed at a time?
Thanks in advance for any help/suggestion in this regard.
