> This should help a bit more, does it make a difference for you? My previous test wasn't really good for measuring it. I hacked a micro-benchmark, which confirms that the patch improves performance a lot. It was visible when doing "real" Vulkan vkGetPhysicalDeviceProperties calls in a loop, but even cleaner when I changed it further to make Unix side to be no-op. It closes most of the gap between direct call and __wine_unix_call_dispatcher. Times recorded for no-op calls: - direct call: 5761 - unpatched Wine: 13933 - ret.diff: 6823 (55% time spent in __wine_unix_call_dispatcher, 29% in PE vkGetPhysicalDeviceProperties) Looks impressive! -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1552#note_18474

[PATCH v2 0/4] MR1635: jscript: Implement a Garbage Collector to deal with circular references.
by Gabriel Ivăncescu Dec. 2, 2022

Dec. 2, 2022

Implement a basic GC based on the mark-and-sweep algorithm, without requiring manually specifying "roots", which vastly simplifies the management. For now, it is triggered every 30 seconds since it last finished, on a new object initialization. Better heuristics could be used in the future. The comments in the code should hopefully understand the high level logic of this approach without boilerplate details. I've tested it on FFXIV launcher (along with other patches from Proton to have it work) and it stops the massive memory leak successfully by itself, so at least it does its job properly. The second patch in the MR is just an optimization for a *very* common case. For artificial testing, one could use something like: ```javascript function leak() { var a = {}, b = {}; a.b = b; b.a = a; } ``` which creates a circular ref and will leak when the function returns. It also introduces and makes use of a "heap_stack", which prevents stack overflows on long chains. -- v2: jscript: Create the source function's 'prototype' prop object on demand. jscript: Run the garbage collector every 30 seconds on a new object jscript: Implement CollectGarbage(). jscript: Implement a Garbage Collector to deal with circular references. https://gitlab.winehq.org/wine/wine/-/merge_requests/1635

In a Vulkan sample that I previously used to measure the impact on command buffers, I can see a really nice improvement. If I disable all direct calls, overhead drops from __wine_syscall_dispatcher ~8% (measured in Wine without your recent patches) to 1.05% (and <0.2% for __wine_syscall_dispatcher, so not related to winevulkan). That compares to 0.6% for direct Unix calls. FPS differences roughly match that. It looks promising. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1552#note_18458
