How to reproduce:
1. Extract and open the attached “IN-112617.zip“ project
2. In the Assets, open the “scene.unity“ Scene
3. Enter Play mode
4. Exit Play mode quickly after entering Play mode (This helps reload all resources; the first run may take longer)
5. Enter Play mode
6. Exit Play mode quickly after entering Play mode, otherwise the Profiler will miss the initial frames.
7. Observe the first frame of the Profiler
Expected result: LogStringToConsole function compiled via Burst takes the same amount of time (~0.14ms) as one compiled without Burst
Actual result: LogStringToConsole takes seemingly too long (~0.6ms) as compared to other functions compared without Burst
Reproducible with:
1.7.0-pre.1 (2023.1.0a5, 6000.0.57f1, 6000.2.4f1, 6000.3.0b1)
1.8.24 (2023.1.0a5, 6000.0.57f1, 6000.2.4f1, 6000.3.0b1)
Not reproducible with:
1.6.6 (2023.1.0a1, 6000.0.57f1, 6000.2.4f1, 6000.3.0b1),
1.7.0-pre.1 (2023.1.0a4 (77dfbc7234b7)),
1.8.24 (2023.1.0a4 (77dfbc7234b7))
Reproducible on: Windows 11, MacOS 15.6.1
Not reproducible on: No other environment tested
Notes:
- Since the expected runtime for the function is not defined, the increase in execution time is interpreted as a regression in this case
- The times mentioned in the “Reproducible with“ section near the version number, are timings of the LogStringToConsole function, as seen in the Profiler
