Great, thank you!

P.S. what is the default cache size?

Ah, sorry, I'm getting mixed up between the total number of blocks which can be stored in memory, vs the number which can be stored uncompressed.

The block cache size is the number which are uncompressed and defaults to 256 - you can probably leave this as it is.

The tatal number in memory is controlled by setMaxBlocksLoaded() and defaults to 4096. This is actually the one which triggers the streaming, and you can try increasing it (no promises!)

Some of these names may change in the future...
