Please post questions like this to one user list that is relevant to it. The devel lists are for developers of the software to discuss bugs and new features not for user requests.
The short answer is to follow the advice in GeoServer in Production: we do it, here is how! about how to prepare imagery. Jpeg and JPW is a slow format compared to GeoTiff.
You might also benefit from watching Earning your support instead of buying it, to help you work out which mailing lists to use.

Hi All,
I am publishing 100 Gb of aerial image til on GeoServer using pyramid technique. I have made GeoServer in a production environment according to GeoServer manual “Running in a production environment”. I have prepared data using gdal_retile:

Intel Xeon E5, 2.20GHz (2 processor) and 32gb RAM. But when I am accessing this layer using WMTS service, it is taking a lot of time(around 30-40 minutes)to load completely in Qgis and ArcGIS at resolution 1: 2000000.Can anyone suggest me how to reduce rendering time?
Thanks and Regards
