各种UNIX文件程序的基准

Description copybench includes various filecopy programs in different implementations for UNIX environment. Purpose copybench may be used as the benchmarking program for Storage Hardware and Operationg System (e.g. I/O, Memory, File System). Detail copybench includes following implementations. 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
