Library:
--------

+ - Paged Aggregation
+
+ This is one of the file space management strategies. This strategy
+ aggregates small metadata and raw data allocations into constant-sized
+ well-aligned pages, which are suitable for page caching. Paged
+ aggregation together with the page buffering feature will allow efficient
+ I/O accesses.
+
+ - Page Buffering
+
+ The page buffering layer in the HDF5 library absorbs small accesses to
+ the file system. Each page in memory corresponds to a page allocated in
+ the file. Access to the file system is then performed as a single page
+ or multiple of pages, if they are contiguous. This ensures that small
+ accesses to the file system are avoided while providing another caching
+ layer for improved I/O performance. This feature works in conjunction
+ with the paged aggregation feature.
