Bad performance after upgrade to snap

Community Support
1

Hi,

we have upgrade our old rocketchat server from 4.1 → 4.7 → 5.7 → 6.4.
We used a fresh installed server (ubuntu 22.04), installed rocket chat
using snap on the system and restored the backup. Everything went well.
We updated step by step and checked the result → everything working!
But the system is now running very slow. Whenever you try to download some
pdf or xlsx it takes minutes.
Using the app on a handy downloading is impossible!

So why is the new version running as snap package so much slower ?
Where can we look for some improvement ?

Any help is welcome!

Bye,
Peer

So we have tried to extend the memory (32G now) → no effect.
In the log the following error occurred:

There is no folder created below /tmp.
ll -d /tmp
drwxrwxrwt 13 root root 4096 Oct 20 09:26 /tmp/
or is it a relative path within snapper
