@privsec Not currently but this will be a problem when we upgrade the mongodb addon to use Mongo 5.x and beyond. Currently, it is on Mongo 4.4 which is reaching end of life sometime next year.
So, unfortunately, we have no choice but to stop supporting servers which have no AVX when we upgrade Mongo.

cat /proc/cpuinfo | grep -i avx
I have avx on my system.
AVX was launched ~2011 (https://en.wikipedia.org/wiki/Advanced_Vector_Extensions)If a new system doesn't support avx, it's likely a celeron system or a lower speced system.

For those who are on Windcloud:
The default flags are

As per support, the following flags can be activated upon request (just open a ticket):

The change requires a complete shutdown (restart is not enough). I have mentioned that future Cloudron versions will require the AVX flag to be set, so they might change the default setting for new Cloudron VPS orders. But better double-check...

For my main cloudron, I'm using a netcup VPS which doesn't have AVX extensions. I could change to a bigger RS server there, then I'd be able to use AVX. Would be more expensive though.
At home, I have an Odroid H2 with Proxmox and Synology DS720+, both are using a Celeron J4105 / J4125 which don't have AVX, both are not too old (2 years or so).When looking around, I noticed that the FreeBSD guys didn't like the AVX requirement as well and compiled recent mongodb versions without avx flag for their ports, maybe that would be an option for cloudron as well?

For home server users like me: the CPU requirements are quite steep: i3 and up (no power saving - i.e. fanless - Pentium or Celeron) and even then youโre not save (from https://github.com/docker-library/mongo/issues/485#issuecomment-891991814) :
For Intel x86_64, MongoDB requires Sandy Bridge or later.
For AMD x86_64, MongoDB requires Bulldozer or later.Starting in MongoDB 5.0, mongod, mongos, and the legacy mongo shell no longer support x86_64 platforms which do not meet this minimum microarchitecture requirement.
https://docs.mongodb.com/manual/administration/production-notes/#x86_64
the underling requirement for the MongoDB 5.0 binary server packages is CPUs with AVX instructions. These are broadly Sandy Bridge or newer Intel CPUs, but there is a caveat:
Not all CPUs from the listed families support AVX. Generally, CPUs with the commercial denomination Core i3/i5/i7/i9 support them, whereas Pentium and Celeron CPUs do not.

I've been meaning to do this myself but haven't got around to it. Did you get a response? What did they say? thanks!
