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.
I'll point out the obvious, which is that it is an apples-to-oranges comparison.

For it to be a fair comparison, it should have been made on the same exact hardware, and with the same LTspice*.ini file.? Neither of those is true.? How that skews the results, I can't say but it might be very significantly.
Windows : 1min 39s
Linux 1 : 0min 21s
Linux 2 : 0min 30s
For kicks, I tried this on an old Windows laptop here, with much less memory and a different CPU.? So it is difficult to compare expectations, except? that I would have expected mine to be slower than yours.??But somehow mine was about 6 to 9 times
faster than yours!? And two to three times faster than your Linux tests.? And I had marching waveforms enabled and even plotting a waveform, which made mine run slower than it could have done.

That has me wondering.? What were your LTspice settings that made it so slow?? What else might have been running on your computers?

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.
Maybe it was still in the way and holding things up.? That significantly?? Perhaps.

I am not currently set up with Linux.
