Hm. ZeroTier has had hardware acceleration on the ARM64 platform since version 1.6. RouterOS’ package is currently at 1.10.

Did MikroTik actively disable this on their build?

Only AES-NI.

While ZeroTier will operate on very low-power hardware (e.g. a single core 32-Bit ARM running at 600Mhz without AES hardware acceleration (AES-NI)), its performance will suffer.

Since the L009 has an arm64 CPU, why would they not be using 64-Bit RouterOS on it to begin with?

That's a question unanswered from the very first time this device was releases.

EDIT: or was it ?

But given that reply, why 64 bit on RB5009, AX2, AX3, ... ? They don't have 2Gb RAM.

If you're planning on embedding ZeroTier in a product such as a router, network attached storage or some other IoT application we see that our partners have a better experience with 64-bit ARM as opposed to 32-bit ARM since the core speeds are typically higher and the chips are more likely to have AES-NI.

As far as encryption/ciphers goes including ZeroTier and many others, please correct me if I'm wrong, but isn't 64-Bit CPU/Kernel/Host OS the De facto industry standard across the board?

Then their faq page is inconsistent.

Mikrotik marches to their own beat. I'd like to think they tested it.

While dunno know enough about ARM assembler to say much (nor IPQ5018's specifics), ARM's docs suggest encryption extensions are in the 32-bit:

It's kinda hard to check if ZeroTier/etc are using them. I'd like to think so... e.g. never seen ZeroTier cause sustained high CPU... now never systematic tested with large traffic volumes either.

Enter Mikrotik BTH ...
(or setup your own WG server and work from there)

Thank you, but it looks like a rather old post from Sep '23. I can't find any statement from ZeroTier regarding a new license model and it seems more like two customers have complained about incorrect license quotes.
