Am I right to be bothered by this?
The majority of Unix network traffic is handled with read()/write().
Why would zerocopy slow that down?
If zerocopy is simply unoptimized, that's fine for now. But if the
problem is inherent in the implementation or design, that might be a
problem. Any patch which incurs a signifigant slowdown on traditional
networking should be contraversial.
please ignore me if I don't know what I'm talking about.
