Ciao Christian, I think you'd need to be more specific in order for us to be of help. A few questions: - are you using a standalone GWC or the integrated one? - which version? - are you seeding in advance or letting GWC creating the cache as needed? - is disk quota enabled? - what kind of data are we talking about? Has it been preprocessed correctly? - which formats are you trying to serve? PNG, JPEG? - is the cache local or accessible via network A few posts that might help out: http://geo-solutions.blogspot.it/2012/05/tips-tricks-geowebcache-tweaks.html http://geo-solutions.blogspot.it/2012/08/real-world-uses-cases-troubleshooting.html http://goo.gl/74XUPq Regards, Simone Giannecchini == Our support, Your Success!
