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.
