not seeing one from iOS :/
argh, I only just saw this now, and the iOS device is far away now. Rageshake didn't work btw, so it was a manual procedure, which I guess I screwed up.
05:53:29
@madduck:madduck.netmartin ➬I will try again somehow.05:54:00
@julien.dauphant.beta.gouv.fr:matrix.orgJulien D.Hello Everybody 👋 What's are the actual limit of devices/users in an encrypted room before having performances issues ? (Someone suggested 50 in synapse admin) Do we have solutions to optimize that ? (Before we got MLS) Will the clients Rust crypto lib help on the way ?09:23:51

obviously, there is not a hard limit: it's just slower with more devices.

Hopefully the rust implementation will be faster, but it's hard to say right now.

martin ➬: I am trying to correlate your rageshakes with the screenshot in https://github.com/matrix-org/olm/issues/84. Can you tell me the event id of that event at 19:01 -- or at least the date and timezone?
10:19:56
@richvdh:sw1v.orgrichvdh hrm well, I found the 03:24 event and it doesn't appear to have been sent by these devices 10:31:06
@richvdh:sw1v.orgrichvdhoh that's because it's from a different user10:40:01
@richvdh:sw1v.orgrichvdhahhh I have a pair on the 20:12 event10:42:05
@richvdh:sw1v.orgrichvdhhave updated the issue11:05:21
@madduck:madduck.netmartin ➬ thank you richvdh: 11:56:44

I had it working fine with around 1000, but after that there is a delay of more than 1 second to send new messages every 100 messages. And be aware that Synapse restricts you to 500 devices per user or so

Thanks for your feedback, you mean 1000 users or 1000 devices ?
17:31:14
@deepbluev7:neko.devNico1000 devices, was about 5 users17:39:52
@ninchuka:envs.netninchukaI thought you meant 1000 users not 1000 devices17:40:12
@deepbluev7:neko.devNicoIn many cases those numbers are very close either way17:40:47
@julien.dauphant.beta.gouv.fr:matrix.orgJulien D.Is old devices with no more temporary keys left on the homeserver are counted in that number of devices ?18:56:45
@ninchuka:envs.netninchukaif they are logged in I think they are counted18:57:15
@deepbluev7:neko.devNicoThey might still have a fallback key19:17:14
