[question] zero-copy support/example #223

Open alagalah opened 8 years ago

If there is a mailing list to ask questions please feel free to redirect and close.

Is there an example of using LKL for socket zero-copy operations as per http://netdevconf.org/1.2/session.html?jerry-chu ?

Are there examples of using HIJACK with this?

Mailing list is located at https://www.freelists.org/list/linux-kernel-library, but I don't mind continuing the discussion here.

zero-copy is something that @hkchu has been looking into, I'll let him answer that.

Unfortunately we hit some road block so this is still WIP. Please stay tuned.

Can you share the issue? Best I have been able to come up with is single memcopy between containers.

It depends on what configuration you have and which copy you're referring to. E.g., one of the configurations we use involves 6 copy operations for each byte transferred. Different copy operation poses different challenge...
