mimalloc VS hardened_malloc

Switching to jemalloc or mimalloc doesn't improve the performance either.

mimalloc: mimalloc is an open source implementation of malloc, currently the best performing allocator.

Some compiler writers thought that was the case, if [0] is related to OP. I don't have a "modern" (after 6th gen) Intel CPU to test it on, but note that most programs are compiled for a relatively generic CPU.

Yes, it's very efficient and that's not where the main problem lies. However, small allocations with modern C heap allocators like mimalloc or snmalloc has gotten extremely efficient as well. Would be interesting to see a benchmark comparison with Java's G1 and ZGC.

Memory management for C is not itself a solved problem, not only is there a lot of performance to squeeze out of malloc itself (the benchmarks on https://github.com/microsoft/mimalloc exemplifies the variance between the implementations), but it's up to the programmer to implement memory management in the large in an efficient way, which is not an easy task. One sure mark of a slow C program is one with a ton of mallocs and frees strewn all over.

It's a very terse howto for replacing Factorio's memory allocator with Microsoft's mimalloc, and configuring mimalloc so that memory is always allocated on huge pages by using madvise().

I was wondering if Koka's perceus referencing counting style is any different from the reference counting that Lean4 implements? I understand that both rely upon the mimalloc (https://github.com/microsoft/mimalloc) library in the backend.

If you are fine with heap allocations then there are only few dozens operator new/delete to override to regain control over normal C++ code memory use. Allocators and STL all need to call those. At least that's what gaming does on all platforms. If you need examples you can check Mimalloc on github ( https://github.com/microsoft/mimalloc/blob/master/include/mimalloc-new-delete.h ).

What's the difference between this and Microsoft's? https://github.com/microsoft/mimalloc

Would grapheneos (https://grapheneos.org/) help with this? I am using a pixel 4a as a "house phone" so it is plugged in all the time but I wonder if I should upgrade.

If you're willing to buy a new device, then I recommend getting a Pixel on sale and flashing it with GrapheneOS[0]. No rooting required. Read up on it when you have a chance. Also, if you install the sandboxed Google Play Services layer (which doesn't require any Google account logins and has very limited access to the device) you will be able to run your bank app.

It might be worth to switch to GrapheneOS if you have Pixel phones: https://grapheneos.org/

It is a more serious project than LineageOS in the sense that they take security very seriously and they take their development more professionally too. There are no disadvantages to using GrapheneOS compared to LineageOS.

You can see a comparison here: https://eylenburg.github.io/android_comparison.htm

If it still powers up but just won't boot you could try installing https://grapheneos.org/.
