Hi,
We have a GeoServer2.1.0 with Oracle plug-in deployed on Weblogic as an application. We have created layers for the Oracle Spatial data for projection on BIng maps. We are facing performance issues with a single overlay taking around 35 seconds to render on screen. On analysis of the GeoServer log(snippet below), it is noticed that there is a gap between 2014-08-20 15:37:03,232 and 2014-08-20 15:37:07,662. Is it the database queries running for 4 seconds? We are using JDBC connection pools to connect to the Oracle database. The spatial indexes have been analysed recently. Any suggestions to tune the database or tips to improving the performance will be highly appreciated.
