I had an impression already that Linux/Wine is a faster platform for LTspice than Windows. Now I have a data point to demonstrate it.
The file is uploaded, belka.asc .? It is a simple RF mixer with a BJT audio amplifier. It runs 5ms of transient analysis. The simulated RF frequency is 4MHz.
The LTSpice version is 24.0.12 on all 3 computers I compared.
Windows computer is Asus Vero laptop, i5-1235U, 16GB RAM, Windows 11 with all latest updates.
Linux computer 1 is Dell Precision 5530 laptop, Xeon E-2176M CPU (8th gen core),? 32GB RAM
Linux computer 2 is Asus ZenBook 14, i7-8565U, 16GB RAM
The Linux OS on both is Mint 22.1, recently updated. Wine is the latest from the repository, no tweaks.
Now to the numbers. I pushed the start button and timed it to the button turning green again. No traces displayed, no previous runs (fresh window).
Windows : 1min 39s
Linux 1 : 0min 21s
Linux 2 : 0min 30s
I tried to add a security exception for LTspice in Windows, so that the real-time antivirus is not in the way. It is known to slow down many applications. There was no noticeable difference.
If you look at the single thread benchmarks for these CPUs, i5-1235U is expected to be about 50% faster than both of the 8th gen CPUs, although Xeon has similar multithreaded score.

I invite other people to reproduce and to try different files.
