Days of yore, and log-stream gore.
Okay, it wasn't that long, but a bit more involved than I had expected. The latest
commit on aleph now uses a zero-copy, per-interface coalescing transmit buffer on
BackboneInterface. I've also optimized memcopies almost entirely away on HDLC deframing.
And added full, memory-bounding dataplane egress control. Parameters will most probably
need tweaking; it's the wild west at HEAD right now, yall. Does it all
work? I think so. Will there be bugs? If not, I deserve a beer or something.
The intention of all this memcpy schything is to significantly reduce memory bandwidth
requirements for all the core ingress/egress and buffer operations. There's still
low-hanging fruit left, but this should take care of most of it.
Whether it provides a decent performance improvement on slower hardware remains to be
seen; I haven't tested it yet, caus I need to sleep. But on my laptop at least, it pushes
resource transfers from ~670 Mbps to just shy of 1 Gbps, so something it did.
Also, the dataplane egress control serves, among other things, to set hard memory bounds
on TX buffer mem consumption (needed the coalescing buffer done first before I could add
that), which could be the cause of your RSS growth @K8. I want to yabber on about it all,
but I am falling asleep in my chair.... gnight.

Bugs or no bugs, you definitely deserve a beer! Thanks for all the performance
improvements packed into this humble patch release (1.5.1 is out). And thanks to K8 for
the live profiling, you deserve a beer too :)
Seriously, we're lucky to get all of this for free. I'm so grateful for all the hard work
you've put into improving Reticulum. For those who haven't donated to Mark yet, you know
what you should do!

Definitely big thanks for all the work that went into this release. Even better than
thanks, though, here's more data! ๐ https://pastebin.com/p0pdwz65
There were 235 clients when I pulled those numbers. Things are looking better across the
board, though there are still some spikes. The CPU usage on the node is MUCH improved,
though, and it's been running more smoothly and more quickly than it has in a long time.
I'm also dropping a lot fewer packets in the queues. I'll keep an eye on things and see
how it looks after a week.
The protocol violation stats are interesting. I only have two interfaces with any (both
are just running plain rnsd as far as I know), plus some more from other
clients in the logs. It looks like they are all coming from malformed packets with
too-high hop counts. Most of them are just 128 hops, and a handful have much much higher
counts.
