High memory since 0.3
Since updating Ajour to iced 0.3, we have noticed very high memory on especially Windows.
| Windows | MacOS | |
|---|---|---|
| iced 0.3 | ~195mb | ~90mb |
| iced 0.2 | ~70mb | ~70mb |
Here's a picture of Windows running Ajour with both 0.2 and 0.3, both builds built in release mode.
It should be quite easy testable master runs 0.2 and development runs 0.3.
Can confirm same issue here on windows.
The issue isn't present on Linux, pre /post the 0.3 commit its at ~112mb on my machine.
There's a post in the Zulip about this. Memory usage has increased noticeably ever since upgrading the wgpu dependency to 0.6, and 0.7 made it even worse. The glow renderer is fine, so something is up on the wgpu side of things.
@Ssaely Thanks for the heads up on that.
I wish I knew more about profiling on windows to help figure out what's causing this. We have some really cool features dependent on 0.3, but we're hesitant to roll this out when memory usage is ~3x and one of our selling points is performance :P
that's awesome ajour uses iced, didn't know that, absolutely love Ajour so thanks for your team :). On this issue, I tried the fix that helped the #786 example, but it didn't change anything here. Going to try and take a look, was hoping 0.8 would have helped also but it didn't, so it's probably some niche usage of wgpu
and as a note, iced examples do it too, so it's not something specific to ajour either (also makes less code to look at)
EDIT: It appears to be a buffer in wgpu_glyph, still researching but at least narrowed it down to that
created issue: https://github.com/gfx-rs/wgpu/issues/1407
With the fix it runs at ~68mb on 0.8.1
Running the simple "Hello World" example from the Application trait with tokio feature enabled ate 180 Mb ram on my Win10 ... I guess the same example would only use a few Mb with fltk-rs. Wonder why this uses such high memory.
