坑爹。。为什么下载或传输速度只是预期的1/8?

When it comes to throughput measurements, however, both bits and bytes are used, so you
have to be careful. Raw throughput values are normally given in bits per second, but many
software applications report transfer rates in bytes per second, including many Web
browsers and FTP client programs. This often leads to users wondering why they are only
getting one eighth of their expected download or transfer speeds.
