Memory Leak?

[Nejat]

Hi,

I noticed a steady decrease in ui response in my new desktop app, which led me to discover a steady increase in memory consumption using the Window's Task Manager. As the memory usage climbs the UI response slows down, otherwise it starts out very responsive.

The app uses several context providers, all of which wrap the values in a Signal, except for the one value passed in through the LaunchBuilder. There are also several use_signal hooks.

• All Signals are created in a hook.
• Some Signals are passed to components as properties and a local function.
• A lot of the Signals are read() or write() to pass immutable and/or mutable references to an external library.
• Most of the values implement Copy (between 8 and 64 bits).

There are over 700 elements on the page and clicking any of them modifies the state.

I tried the following code changes with varying degrees of success:

• I don't know if it is supposed to make a difference but the first thing I did was implement Eq, PartialEq on the remaining few of the structs that did not implement it. did not make any difference

• changed the two Vecs to be updated in place instead of being completely replaced. seemed to make a small difference

• commented out the one very frequent update all together. seemed to make a much bigger difference, at least it slowed it down a lot

However, the problem persists.

Any advice on how to track down the issue?

Unfortunately it's not open source code.

Thanks for the help,

btw, the app starts out at about 7.8 MB and steadily climbs from there. At first, it was in increments of 1 MB but I did manage to slow it down to about increments of 200-300K.
