Messages are taking a long time (+30m) to decrypt in rooms, presumably this is database slowness but could it really be this slow. Other devices/clients aren't showing any unable to decrypt errors.

Is this by any chance related to #1721?

Hello, it looks like the crypto module has been jammed by fluffy chat key request spamming that leads to a crash in sync and a desync of olm sessions
1.0.10 (currently in process of beeing released) added mitigation to prevent key request jamming.
In parallel we started an effort to ensure atomicity of syncs to avoid such desync
