所使用的环境由与MACVLAN一起使用的两个docker容器以及一些噪音流量(产生大约±1%的错误)组成。在我的情况下,fileX是一个二进制文件
因此,以下是rsync tarred文件与带有压缩(选项-z)的rsync untarred文件的结果
1. File tarred + rsync without compression (rsync -axvPAH fileX.tar destination:/path)
File size is 56933 bits (fileX.tar)
Transfer difference is 4735665-4673346=62319 bits
2. File tarred + rsync with default compression (rsync -axvPAH -z fileX destination:/path)
File size is 56933 (fileX.tar)
Transfer difference is 4933845-4871608=62237
3. File tarred + rsync with maximum compression (rsync -axvPAH -z --compress-level=9 fileX.tar destination:/path)
File size is 56933 bits (fileX.tar)
Transfer difference is 4870664-4808387=62277
4. File untarred + rsync with default compression (rsync -axvPAH -z fileX destination:/path)
File size is 237525 bits (fileX)
Transfer difference is 4669946-4607637=62309 bits
5. File untarred + rsync with maximum compression (rsync -axvPAH -z --compress-level=9 fileX destination:/path)
File size is 237525 bits (fileX)
Transfer difference is 4806735-4744764=61971 bits
6. File untarred + rsync without compression (makes no sense since it’s the most bandwidth consuming one)
