Iozone reports thusly: According to your iozone results, reads on 2.0 are twice as fast while writes are slightly slower. The specific problem regarding performance of 'man' is likely caused by differences in the way that the manual pages are stored. 2.0 stores the manual pages in gzip compressed nroff format to save space, while 1.x installed the manual pages in uncompressed 'cat' format. Also, the cat directories aren't part of the 2.0 distribution, so the system must uncompress and format the manual page every time 'man' is used on it. If you create 'cat' directories, the system will keep the uncompressed 'cat' format page around for future lookup. Hope this helps. -DG
