We’re excited to announce the release of Stalwart v0.12, a significant milestone that evolves Stalwart from a powerful mail server into a complete, integrated communication and collaboration platform. This release delivers one of the most anticipated features from our community: native support for calendars, contacts, and file storage—all built directly into the server, with no need for third-party integrations.

I had to give up on stalwart because on 4gb ram dual core with mechanical HDD the performance for a single account domain was abysmal and after some support back and forth there was no solution.

On the same hardware the good old postfix+dovecot just handles perfectly with 90% spare capacity

Sorry guys, maybe it was time to optimize it a bit before adding more features?

[-] [email protected] 19 points 6 days ago

It's a 0.x release. It makes sense building the intended features first before optimizing heavily. There's no point having an optimized data structure that then falls flat once you need to add new features that brings new requirements to the data structure.

Once they label it 1.x (i.e. feature complete and production ready) I would expect it to be optimized. If it isn't, criticism is warranted.

Stalwart probably aims a bigger infra than mine, i think that is the point.

[-] [email protected] 1 points 5 days ago

It aims at both, otherwise it wouldn't ship with sqlite and rocksdb. Stalwarts default is clearly for single node setups and expanding it to clustering takes further steps. So while it supports large scale deployments, it should not be limited to it.

Are we sure they are using semantic versioning?

[-] [email protected] 3 points 5 days ago

We can ask, but the indicators are there:

  • it has roadmap with bigger features that slowly shrinks as they get implemented
  • new versions still bring big reworks (I think this is the third time now that the data structure is being migrated)
  • optimizations happen between the versions
  • benchmarks are still on the horizon

Mm, interesting.

[-] [email protected] 5 points 5 days ago

That's probably because you were using RocksDB as a backend, which does not work well on mechanical HDDs. Try using PostgreSQL instead.

[-] [email protected] 1 points 5 days ago

I did, we discussed this on an issue and a github discussion. It was still too slow and saturating my low spec machine, no matter which backends I tried to use.

Probably my hardware is just too underpowered.

They have improved performance in this release, although judging from their release notes it is targeting larger infra, so I don't believe these improvements would benefit your setup. Still, good news for software this new.

[-] [email protected] 2 points 6 days ago

@warmaster @Shimitar Their licencing suggests they are targetting larger infra.

[-] [email protected] 1 points 6 days ago

Yeah, that's what I said in the post you're replying to. Is this a case of weird cross-platform federation?

[-] [email protected] 1 points 5 days ago

@warmaster I was just agreeding and suggesting that their monetisation strategy is licencing hence the reason for improvements for Enterprise clusters rather than focusing on Self Hosting is the money.
