bonnie++ results
i was curious what would cause bonnie to report +++++ in a field
after running a test:
mail:/blah# bonnie++ -d .

From "man 1 bonnie++"
For every test two numbers are reported, the amount of
work done (higher numbers are better) and the percentage
of CPU time taken to perform the work (lower numbers are
better). If a test completes in less than 1 second then
the output will be displayed as "++++". This is because
such a test result can't be calculated accurately due to
rounding errors and I would rather display no result than
a wrong result.
Also I think that a problem is that you probably have more than 200M of RAM
and thus most of the test is testing cache not hard drive. Use version 1.01
of Bonnie++ (which is in woody) and it'll automatically choose a suitable
test size for you, or you can do "bonnie++ -r XXX" where XXX is 2*RAM
(measured in megabytes).
As for the last line, again from the man page:
OUTPUT
The primary output is plain-text in 80 columns which is
designed to fit well when pasted into email and which will
work well with Braille displays.
The second type of output is CSV (Comma Seperated Values).
This can easily be imported into any spread-sheet or
database program. Also I have included the programs
bon_csv2html and bon_csv2txt to convert CSV data to HTML
If the man page is unclear then please tell me in which way you find it
difficult to understand and I'll put a better man page in the next version.
Also in future please CC messages regarding Bonnie++ or Postal to me and I'll
reply faster. I'm not on debian-user and I was forwarded the message by a
friend who noticed that I didn't reply.
