|

|

|
|
+ .Sh DESCRIPTION
|
|
+ .Nm Bonnie
|
|
+ tests the speed of file I/O from standard C library calls.
|
|
+ It reads and writes 8KB blocks to find the maximum sustained
|
|
+ data rate (usually limited by the drive or controller) and additionally
|
|
+ rewrites the file (better simulating normal operating conditions and
|
|
+ quite dependent on drive and OS optimisations).
|
|
+
|
|
+ The per character read and write tests are generally limited by CPU speed
|
|
+ only on current generation hardware. It takes some 35 SPECint92 to read
|
|
+ or write a file at a rate of 1MB/s using getc() and putc().
|
|
+
|
|
+ The seek test results depend on the buffer cache size, since the fraction
|
|
+ of disk blocks that fits into the buffer cache will be found without any
|
|
+ disk operation and will contribute zero seek time samples.
|
|
+ (See
|
|
+ .Sx BUGS
|
|
+ below.)

|
|
+ .Sh OPTIONS
|
|
+ .Bl -tag -width indent
|
|
+ .It Fl d Ar scratch-dir
|
|
+ Specify the directory where the test file gets written. The default
|
|
+ is the current directory. Make sure there is sufficient free space
|
|
+ available on the partition this directory resides in.
|
|
+ .It Fl s Ar size-in-MB
|
|
+ Specify the size of the test file in MByte. This much space must be
|
|
+ available for the tests to complete.
|
|
+ .It Fl m Ar machine-label
|
|
+ Specify a label to be written in the first column of the result table.

|
|
+ .Sh BUGS
|
|
+ .Nm Bonnie
|
|
+ tries hard to measure disk performance and not the quality of the
|
|
+ buffer cache implementation. In merged buffer caches common today,
|
|
+ the buffer cache size is often only limited by total RAM on an otherwise
|
|
+ unloaded system. Be sure to use a file at least twice at large as
|
|
+ available RAM to protect against artificially high results.
|
|
+
|
|
+ There is no way to keep the buffer cache from increasing the reported
|
|
+ seek rate. This is because the fraction of accesses corresponding to the
|
|
+ amount of the file cached, will be done without seeks.
|
|
+ If your buffer cache is half the size of the file used, then half the
|
|
+ requests will be satisfied immediately, and and the seek rate printed
|
|
+ will be twice the actual value.
