All,
We have a setup which includes GWC that sits in front of 4 Geoserver instances.
We know the GWC caching is working because after an initial request,
subsequent requests complete quickly from the cache until the tiles requested
are cleared. Once the request goes to Geoserver again the requests are slow.
These requests are taking 15-20 seconds when hitting Geoserver. This length of
time is unacceptable.
I've used Geoserver logging to test the queries being executed directly against
the database and they're completing in < 40ms so I know the problem isn't
there. We've started running tests by requesting tiles directly from the
Geoserver instance and we're able to reproduce the long load times. We are
using a Default metatile size @ 4 x 4. We have 2 Default Cached Gridsets for
the 4236 projection and the 900913 projection, each at the 256x256 dimension.
Are there any tips and tricks for making this loading move faster? Any ideas
on what could be causing the long load times? I can provide additional details
of our setup as well.
Thanks in advance!
