- mmap -> mmap -> memcpy (default, +madvise)
- mmap -> write (default, +madvice)
- read -> write (default, +posix_fadvise)
Build
You can build copybench by the following commands.
$ ./configure $ make
If you got the source code from svn, you need to execute ./autogen.sh before executing configure script.
Execute
First, you need to create large empty file by dd command. This command creates 5G file.
$ dd if=/dev/zero of=5Gfile bs=1G count=5
Then, edit following part of test.sh to appropriate path.
SRC=/data/5Gfile DST=/data2/5Gfile
Finnaly, please execute test.sh.
$ ./test.sh
During execution, you need to input sudo password for clearing buffer cache.
