File.Open, Read and Write operations get slower as the cache size grows on Linux
How to reproduce:
1. Open the user attached project (FurnitureLoadingUnityProject.zip)
2. Open the scene "CacheTest.unity"
3. Enter PlayMode and wait until the Console outputs "Bye" or the 5th stage throws errors (if errors are thrown on the second or fourth stage leave and reenter PlayMode)
4. Open the "EmptyCache" and "FullCache" files, created in the root of the project directory, in the Profiler and pull them into the Profile Analyzer
5. Compare the data and observe the timing differences of "File.Open", "File.Read" and "File.Write" operations
Expected result: There's little to no difference in "File" operation performance
Actual result: The "File" operations are slower when the cache is full
Reproducible with: 2019.4.28f1, 2020.3.13f1, 2021.1.13f1, 2021.2.0b1
Couldn't test with: 2018.4.35f1 (Doesn't run the reproduction scripts due to missing required packages)
Notes:
1. Reproducible on Ubuntu 18.04
2. Not reproducible on Windows 10
