Re: [Python-Dev] [Python-checkins] cpython: Switch subprocess stdin to a socketpair, attempting to fix issue #19293 (AIX

"For the record, pipe I/O seems a little faster than socket I/O under Linux" In and old (2006) email on LKML (Linux kernel), I read: "as far as I know pipe() is now much faster than socketpair(), because pipe() uses the zero-copy mechanism." https://lkml.org/lkml/2006/9/24/121 On Linux, splice() can also be used with pipes for zero-copy operations. I don't know if splice() works with socketpair(). Well, I don't think that Python uses splice() now, but it may be interesting to use it. Or sendfile() uses it maybe internally? Victor
