vmsplice() Versus COW |
|
"While explaining the new splice() and tee() buffer management system calls, Linus Torvalds made reference to some possible future extensions. This included vmsplice(), a system call since implemented by Jens Axboe "to basically do a 'write to the buffer', but using the reference counting and VM traversal to actually fill the buffer." Reviewing the implications of using such a system call lead to a comparison with FreeBSD's ZERO_COPY_SOCKET which uses COW (copy on write)."
