Terminology: opposite of "zero copy"?
We're benchmarking some code that we've converted to use sendfile(), the linux zero-copy system call. What's the term for the traditional read()/write() loop that sendfile() replaces? I.e., in our report I want to say "zerocopy is X millisecs, and ??? is Y millisecs." W开发者_开发知识库hat word/phrase should I use?
"Traditional data copying approach"
Programmed I/O (PIO)
would be appropriate, I think.
Just "copy"?......
