+Performance Improvements
+========================
+    This release of the HDF5 library has been extensively tuned to improve
+performance, especially to improve parallel I/O performance.
+    Most of the specific information for particular performance improvements
+is mentioned in the "New Features" and "Bug Fixes Since HDF5-1.4.3" sections
+of this document, but in general, the library should make fewer and larger
+I/O requests when accessing a file.  Additionally, improvements to the parallel
+I/O portions of the library should have reduced the communications and barriers
+used in various internal algorithms, improving the performance of the library.
+    However, with the extensive changes to some portions of the library that
+were required for these improvements, some errors or unanticipated results may
+have been introduced also.  Please report any problems encountered to our
+support team at hdfhelp@ncsa.uiuc.edu.
+    Hopefully these improvements will benefit all HDF5 applications, but if
+there are particular I/O patterns that appear to be slower than necessary,
+please send e-mail to hdfhelp@ncsa.uiuc.edu with a sample program showing the
+problem behavior and we will look into the issue to see if it is possible to
+address it.
