AcCoreConsole is slower in 2025

[drewbb]

I was having performance issues with AcCoreConsole.exe in 2025.  So I did a comparison of speed between 2025 and earlier versions.  I processed 95 drawings with a very simple script:

(command "zoom" "e")
(command "regen")
_.close
y

Here are the results:

2025 = 277 seconds
2024 = 121 seconds
2023 = 104 seconds
2022 = 103 seconds

Here are the results when running in parallel (Parallel.ForEach):

2025 Parallel = 112 seconds
2024 Parallel = 50 seconds
2023 Parallel = 34 seconds
2022 Parallel = 28 seconds

Any ideas why 2025 is slower and what we can do to improve it?
