Increase default block size from 4K to 64K. It was reduces 6 yeard ago,
when trees were big and FAST mode was enabled by default.
So small block size doesn't benefits linear I/O operations in FAST and
significantly slowdowns in ECONOMIC (default) mode. For single stream random
I/Os so small block doesn't give much benefits, as access time is usually
bigger then transfer time there. Same time it requires all heads to seek
together for every single request, reducing performance on parallel load.
