Cloudron Forum

@necrevistonnezr indeed, previous versions of Cloudron would allocate more memory for redis based on the app's memory limit. This limit was not settable by the user. In 5.2, we have made the redis limits visible and configurable by the user. Our 5.2 migration script should ideally could have been smarter and allocated more memory to redis.

@YurkshireLad The memory recommendation is the absolute minimum memory below which the app won't run reliably. Like even with 1 user, it won't run properly below that recommendation.

The amount of memory required to host 100 users... is hard to know. Usually, the answer to this depends on the how all these users user Rocket.Chat. If they use simultaneously and if they use it from multiple devices etc. Cloudron will give you a notification (email) if an app is running out of memory. So, you can just take it slow and increase the app's memory limit as you go. You can also look into the upstream project's memory recommendation for 100 users.

I manually installed Mastadon on a Digital Ocean 1Gb droplet (unrelated to Cloudron), and with only 1 user and 5 posts, it ran out of memory. I bumped the droplet up to the 2Gb option and it ran smoothly.

@masonbee The memory limit setting is the "maximum memory" before which the app is killed for over use. It is not "reserved memory" i.e it's not pre-allocated to the app and thus cannot be used by any other app. The "maximum memory" simply ensures that a single web app cannot bring down the whole system.

@nebulon It's a good start!

Would be great if you could update this thread with your findings. Also please note that the memory settings for the addons are currently not preserved across app restores or even server reboots. We are working on this fix and you can see the status of it at https://git.cloudron.io/cloudron/box/issues/566
