   unfortunately a known behavior on mobile platforms (especially iOS of course)
   you can try:

   • reducing / cutting geo files to save a couple of mb
   • tweaking memory limits and configuration parameters

   however, these measures are mostly band-aids and won’t solve the root cause...

   xray-core is not optimized for mobile environments
   (for example, when using transports like xhttp, it’s easy to observe goroutine spikes (from ~100 up to several thousand) with light usage - like a few YouTube shorts can trigger this)

   this is a limitation of xray-core itself
   this is something users have to accept and deal with

   Thank you for your patient explanation. It’s very clear and reasonable. I understand it completely. Wish you a good day.

   Both in Happ with xray-core 25.9 and V2BOX with xray-core 25.7 in iOS 18.7, I noticed that the memory used was gradually increasing from around 12M initially to finally 50M and made the app crash.

   It took about from less than one hour to several hours for the final crash to occur.

   If any further info about this topic is needed, I will provide as far as I can.

   Maybe if we can chunk the geo files that can help. But for now HACK: just restart the tunnel when fails.

   I'm using geoip-only-cn-private.dat instead of the full geoip and geosite files, seems to work

   edit: nevermind, it's still slowly increasing but generally it's not an issue. Would periodic manual GC help?

   I’m seeing the same issue on iOS. In my testing, the memory growth comes from the xray-core/Go stack rather than the app wrapper. I eventually rewrote the core in Rust, which resolved the memory problem in my use case.

   Yep, but I made not like saynig codex "make me better lib than xray-core". I passed a lot of agent loops using oracle tests with xray-core. Also, I use benchmarks.
   This library is already integrated into one application (for now only the beta Apple TV version) and also, an application built on this library is currently being reviewed, which works like Streisand or Foxray

   but this really solves the memory problem on iOS
   Besides, I think Rust is better suited for this kind of tasks.

    Good for you man. I don't have money to buy tokens for top tier models :(

    I checked your repo, its 200k + LOC, maybe costed 200/300 $ on tokens :) Huge for just solving mem problem

    Edit :
    @aimalygin do you have tg? I have a really good idea to solve it without so much work, can you send me a hi on tg (same username) or like via mail(check my profile readme)?
