Severe lag moving the drawio window about drawio-desktop

[jeroenvriesman]

Update, I found the cause by measuring the cpu/mem/net stats when moving teh drawio window.
In is indeed related to https://github.com/jgraph/drawio-desktop/1433.
drawio is updating the config.json continuously when the window is moving. For a local filesystem or a high performance network this is fine, but when the config.json is on a network with lower throughput and/or higher latency (for example , working over a company vpn ) this causes the severe lag in window operations like moving or resizing.
Possible solutions:
a) a feature to turn off writing the window position to the json.
b) a feature to choose a local location for the config.json (we also have diskless clients, so this doesn't solve all the problems)
c) make the write to the config.json asynchronous so write latency doesn't affect the application

I think option c is the most general solution. Maybe option a is easy to implement, it would just disable 1433 which is not that important.

We have millions of users on windows, if it were a widespread issue this repo would be underwater. There's something specific to your machine.

Either something like a virus checker that doesn't like a new signature on later releases, or the storage used doesn't like a write or flush change in 22.1.5.

We still cannot repeat. I would suggest to find an alternative tool given the problems you're having.

Cool, thanks for taking the time to investigate and report back.

Will be fixed in the next release
Thanks for the report

Thanks for the fix Mohamed.
Only writing the window info upon close is a indeed a better idea than my suggestion.

Fix in 24.6.1

Hello, still seeing extreme lag in 24.7.8 desktop windows installer.
i7, 32GB RAM, Diagram has ~50 tables.

Are you moving or resizing the window? Is it faster with a blank diagram?
