As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file.

    1 Differences between Bonnie++ 1.00 and 2.00.

    3 Version 2.00 is totally threaded, this has many subtle impacts on the way the
    4 code works.  This changed the per-char results so I decided to make it do
    5 per-byte tests using write() and read() instead.  The results are now much
    6 less.  From 1.92.

    8 When closing files for the IO tests the operation is to fsync() each file
    9 handle.  This means on Linux and other OSs that agressively cache writes the
   10 write performance will be noticably less, but the results will be more
   11 accurate.  From 1.90b.
   12 
   13 The number of seek processes is now 5 instead of 3.  Now almost all new hard
   14 drives have some sort of seek reordering capability, and OSs are getting
   15 smarter about maintaining queues.  This and the increasing popularity of RAID
   16 arrays requires more seek procs to do a reasonable test.
