While a proper configured WMS server is able to serve tiles off nearly all sizes some clients use an algorythm to stitch tiles with same size together. For example google maps usually request 256×256 px wide tiles.
Using bigger tiles leads to less requests against the server and faster display in your internet browser. On the server side the number of different tiles is no longer endless and a caching is an option. Lucian Plesea extended the WMS protocol to a tiled WMS and speeds up NASA’s JPL OnEarth WMS server.
The new map pack (1444) provides all served maps from this capabilities file except the single monthly Blue Marble Next Generation. Most interesting is Daily Terra combined with the 2007 version of Blue Marble as background. Daily Terra is updated every day and the colors match perfectly BMNG.
This map pack requests 512×512px sized tiles, the performance is much better than the standard OneEarth WMS - zooming and moving means more fun now. Unfortunatly WMS overlays do not work with this projection (for now), but all point data (placenames, weather, tropical storms, videos, hotels, photos, … ) are displayed at the right place.
