On: mTCP: A high-performance user-level TCP stack for multicore systems

Interesting. However, Last modified: 2014. There has happened a lot in the Linux Kernel since then. I wonder what the state of the art is nowadays and how it compares to the Kernel.

[jdsully → yxhuvud]

The kernel is still quite slow at handling TCP/IP packets. Its the bane of my existence with KeyDB. I'm still experimenting with io_uring which should help a little bit but that was only released this year.

I'm not claiming it is fast. I'm claiming there is a lot of water under the bridge and development done, both for the kernel and probably also for custom TCP stacks. Hence my call for a more up to date comparison.

That said, indeed, io_uring seems like quite great progress.

[jdsully → yxhuvud]

I should be more clear: From my perspective as someone following this closely little progress has been made. With the notable exception of io_uring.

[grosswait → jdsully]

I wonder if the userspace stack netgate is using in their tnsr product could help?

The mTCP stack is based on the FreeBSD network stack, not the Linux stack. And it has recent activity on GitHub.
