That’s crazy - for typical use it should use about 300MB resident (rsz); up to 1GB for worst case massive account.
What RSZ are you seeing? And how big is the javascript heap? (ctrl-shift-I to open the inspector; go to performance tab; hit heap snapshot to see where the RAM is going).

Hi,
The electron version uses 12 GB of RAM just after starting. This will grow over time, and I've seen it use 60 GB of RAM.
I'm using the .deb package from riot.im. currently using version 1.2.2, but it's not a new problem.

A few minutes after I started it, I get:

And how big is the javascript heap?
It reports things around 300 MB.

right, so that’s 284MB + 40MB + 640MB + 828MB + 118MB of resident RAM. however, some of that might be shared libraries shared between the processes? Will compare with other electron deployments. 300MB js heap is about right. |

So looking at the smaps file, I see things like:

So that's 8 GB - 256 kB, 2 GB, and 1 GB - 444 kB that's allocated
but unused.

So I got his now: |

I have to restart riot on daily basis because it just stops working.
|
|
Riot is just using 11G or ram.... |
|
riot.im/develop (and next point release) fixes a lot of leaks. |

I no longer use riot sorry. |

I guess it's not as bad as it used to be. At start it seems to
require 1.5 GB and then seems to stay stable around 1 GB of used
RAM.

@kroeckx I'm going to close this issue for now as the problems from 2019 have been resolved and the codebase has changed significantly since then. If you feel that there are further improvements to be made, it would be helpful to have a new issue with fresh details. Thank you for helping make Element better! |

Hi,
The electron version uses 12 GB of RAM just after starting. This will grow over time, and I've seen it use 60 GB of RAM.
I'm using the .deb package from riot.im. currently using version 1.2.2, but it's not a new problem.
