Somes Benchmark with readfile

 

Readfile can be used show the speed of checksum computation using different method.

 

 

to use file mapped IO (so when file is in disk cache, we will take only time for computation), use this syntax:

Readfile <FILENAME> b m z <checksum method>

 

where FILENAME is the path of a file

<checksum method> is one or several of :

a : compute Adler32 code (using adler32.cpp from zLib)

g : compute MD5 code using MD5 source from L. Peter Deutsch

        see http://sourceforge.net/project/showfiles.php?group_id=42360

go : compute MD5 code using MD5 source from OpenSSL 0.9.7

c e# : compute CRC32 using one of the source code, where # is :

    1 : CRC32 code from zLib 1.14

    3 : new optimized CRC32 code from zLib 1.21 (see http://www.gzip.org/zlib/ )

 

 

so by example :

readfile c:\download\mozilla-source-1.3.tar.gz b m z c e3

  will test the file c:\download\mozilla-source-1.3.tar.gz using zLib 1.21 CRC32.

 

of course, always ignore the first test, which load the file in system cache

 

I provide executable from both Visual Studio 2003 and Visual Studio 2005 - Community Technology Preview May 2004

 

You can get both source and executable on readfile_vs2005_test.zip.
