To save you the two-link chase to get at the meat of the announcement, here's a direct link to the paper: http://info.iet.unipi.it/~luigi/papers/20160205-tlem.pdf

It explains in a lot more detail than the mailing list post what TLEM is about and how works.

Choice quote from the abstract: "Our emulator can handle bidi- rectional traffic at speeds of over 18 Mpps (64 byte pack- ets) and 30 Gbit/s (1500 byte packets) per direction even with large emulation delays."

and the mismatch between the number in the pdf and the one in the manpage/mail is due to subsequent optimizations.

Ok, we changed to that URL from https://lists.freebsd.org/pipermail/freebsd-net/2016-Februar.... Thanks!

(OP/author here) I think you should have asked before changing the URL.

The original URL pointed to the correct repository and had up to date performance numbers. Now it only points to the paper which is has stale information on both. Any chance to restore the original ?

If we asked before changing every url, we'd do nothing else all day.

I've put it back to the one you want, though I'm skeptical it's a better choice. It seems so to you because you know the project inside-out, but the audience here does not. The best story is the one that explains what it is, optionally with a comment in the thread pointing to updated information.
