[Bug 59514] New: Significant time()/localtime() Performance Regression in Wine 11.4
by WineHQ Bugzilla March 20, 2026

March 20, 2026

http://bugs.winehq.org/show_bug.cgi?id=59514 Bug ID: 59514 Summary: Significant time()/localtime() Performance Regression in Wine 11.4 Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ucrtbase Assignee: wine-bugs(a)list.winehq.org Reporter: wszqkzqk(a)qq.com Distribution: --- Created attachment 80538 --> http://bugs.winehq.org/attachment.cgi?id=80538 Minimal reproducer: time() / localtime() performance regression in Wine 11.4 Repeated calls to `time()` and `localtime()` are significantly slower in Wine 11.4 compared to Wine 11.3. A tight loop calling these functions 10000 times shows a clear regression in per-call cost. The same program compiled and run natively on Linux is orders of magnitude faster, confirming the overhead is in Wine's translation layer. Compared with Wine 11.3, per-call cost increases from about 12.8 us to about 319 us, roughly a **25x slowdown**. ## Environment - Host OS: Arch Linux, Latest - CPU: AMD Ryzen 5800H (laptop without power) - Wine versions tested: 11.3 / 11.4 ## Minimal Reproducer Single-file C program. See in the attachment. Build as a Windows PE executable (e.g. using a Windows-native gcc under Wine): ```bash wine gcc -O2 -o time_bench.exe time_bench.c ``` Build as a native Linux executable for baseline comparison: ```bash gcc -O2 -o time_bench time_bench.c ``` Run: ```bash # Wine wine ./time_bench.exe # Native Linux baseline ./time_bench ``` ## Reproduction Steps 1. Compile `time_bench.exe` as a Windows PE executable. 2. Compile `time_bench` as a native Linux executable on the same machine. 3. Run the PE binary under Wine 11.3 — record the output. 4. Run the same PE binary under Wine 11.4 — record the output. 5. Run the native Linux binary — record the output as baseline. 6. Compare the `ns/call` values. ## Expected Result Per-call cost of `time()` and `localtime()` should be roughly the same between Wine 11.3 and Wine 11.4. ## Actual Result Wine 11.4 shows a significant increase in per-call cost. ### Wine 11.3 ```text iterations: 10000 time() : 0.128437 s (12844 ns/call) localtime() : 0.129727 s (12973 ns/call) sink=17732949360000 ``` ### Wine 11.4 ```text iterations: 10000 time() : 3.196547 s (319655 ns/call) localtime() : 3.184343 s (318434 ns/call) sink=17732948683316 ``` ### Native Linux (baseline) ```text iterations: 10000 time() : 0.000103 s (10 ns/call) localtime() : 0.058464 s (5846 ns/call) sink=17732948500000 ``` -- Do not reply to this email, post in Bugzilla using the above URL to reply.

The common thing between them is they're all .NET application as far as I can tell. The wine's built-in notepad seems to be fine. I currently tested on UndertaleModTool and Margrete and they all crashed. ======EXTRA COMMENT====== As I'm writing this bug report, I did a quick test with Notepad++ and found it also crashed as well. But since I've already packaged my programs and documentation for reproduction, the attachment won't include reproduction for this application. ========================= The attachment is too big to fit into the Bugzilla's attachment uploader so I have to put it on Google Drive and include it as a link. I sincerely apologize in advance for this inconvenience but I just want to make sure it will be reproduced perfectly. The attachment is a .tar.gz which contains two directories, each for one application I mentioned above (not counting the extra comment). In each folder, you will see two important files for reproduction: - A `REPRODUCTION.md` for instructions to reproduce; - A `crash-log` for logs from wine when I'm reproducing it on my machine. The reason why it's that large is because I included complete WINE_PREFIX I used for each application, I haven't tested on empty WINE_PREFIX yet and weirdly though, one of them (UndertaleModTool) needs a very specific WINE_PREFIX to startup properly because Wine's .NET lacking icu.dll.ulocdata_getCLDRVersion and icu.dll.uloc_canonicalize so I had to include the prefix (which is from undertalemodtool AUR package in Arch Linux) to make it work. Again I apologize in advance for that inconvenience.
