There are 2 potential reasons for high meme usage:
- allocator is just not releasing memory after usage, which is fine if you have enough mem available
- there is a mem leak
@xamast_51679 could you check on your side what is the mem usage when you are not running any requests
Then could you check the memory profile as you start doing requests

Not releasing memory is not an issue, if you want the process to use less mem, then limit it, the allocator will just be more savyy
@xamast_51679 do you have a graph of memory before and after the last request ?
I will profile on my side but it would help to understand on your side as well

There are 2 spikes of mem, do they correspond to your requests ?
also near the 0B it was still running right ?

So right now, if you start a clean app, do no request, then meme usage is minimal and only increase when requests are made right ?
Can you do one such heavy request on a clean app and give back the mem profile after it ?
From there I should be able to reproduce and investigate, it might just be the allocator working normally

Thanks!
Sorry for all the requests but it's really much easier for me with reproduction, thank you for your patience

@xamast_51679 can you check if you're displaying virtual or resident memory

Is there a way you can reproduce this with fake bytes generated locally so I can run the same script and investigate locally ?

Also since this is the app and not the worker, could you let me know what interaction you have with it ?

On latest, the mem usage should be greatly improved for apps. We do zero copy result for processing the json
The issue is simply that rust serde is very expensive in memory and we were doing deserialization when we didn't need to
