Hi Andrea, I downgraded the server to 2.4.3 - the issue went away - nice and fast responses.
I've now upgraded to 2.4.6 and the issue came back - the layers are slow again. So something between those versions induces a significant slowdown. To try and answer your questions: - The mosaics are just standard affairs. Irregularly shaped tif files (inner pyramids and tiles) that GeoServer automatically processed. - The index is stored in a shapefile (created by GeoServer) stored with the imageMosaic data. - I'm not sure about imageio reads - where's the config for them? I can't see anything in the store. [image: Inline images 1] Hopefully that narrows what can have caused it. I've opened a JIRA for it too - http://jira.codehaus.org/browse/GEOS-6453 Regards, Jonathan On 15 April 2014 17:54, Andrea Aime <[email protected]> wrote: > On Tue, Apr 15, 2014 at 5:11 PM, Jonathan Moules < > [email protected]> wrote: > >> Hi List, >> I've just noticed that a couple of my layers are taking a super long time >> to load.
