Persistent bitmap caching was added in addition to the memory caching of bitmaps and glyphs that existed in TS 4.0. The bitmaps from the server are now saved to disk on the client machine, which allows cached bitmaps to be reused between client sessions and also provides a much larger cache size (10MB vs. 1.5MB). As seen in Figure 4 (in the linked document), the addition of persistent caching decreases the amount of data sent over the network connection, which in turn reduces the amount of time it takes to render bitmaps on the screen, proportional to speed of the network connection
