Suggestions about reading release notes, etc need not apply -- because the principle of least astonishment (POLA) needs to apply no matter what. Good news: it is incredibly responsive. I have been impressed with it, and the improvements appear real. I am NOT easily impressed. Bad news: the filesystem stuff is a little unfriendly. firstly, it seems to 'modify' already existant FFS filesystems too much to maintain full compatibility with older systems. This is true even when passively doing a mount of older filesystems, and only reading (but not RO.) Also, I am using VINUM with debug mode off, and that has some source code errors for that mode. VINUM has also modified the on-disk structure too much for reverse compatibility (maybe related to other filesystem changes instead of VINUM.) There is *definitely* improvement in responsiveness over older versions of the system. There are also some problems of the code being 'green.' I have participated in worse releases, and 5.1 will probably be incredibly good. A better designed kernel restructuring would have been better, but otherwise, the results are very good.
