I run Emacs on both Linux and Windows and I find that with more or less the same packages, the Windows Emacs tends to "slow down" after a while. I've used the profiler to track down a couple of things that were causing slowdowns (ibuffer auto refresh, etc), but still haven't quite go to the point where Windows runs as fast as Emacs. On both cases I have fairly long running Emacs sessions - around a month on Linux, when I pickup distro updates, and a week on Windows as we do mandatory reboots weekly. I recommend you try profiling to see if something shows up [1].

I spent some time poking Emacs on Windows with a profiler too, also to no avail (few things I identified as suspect turned out to didn't matter). I eventually resigned to running Emacs under WSL1 and rendering it on VcXsrv on Windows side. It's very fast this way, though some filesystem-heavy operations are still slightly slower than they would be on Linux (that's a limitation of WSL and NTFS). About the only issue I have with this setup is that I can't get color emojis to work using Microsoft's Segoe UI Emoji :). That, and if I want to call out to some Windows executable, I have to ensure I use :connection-type 'pipe instead of (the default) TTY in make-process, because otherwise I get a disconnected process that can't communicate with Emacs. But the latter is a very rare case (I only need it to drive the build system I use at work from Emacs, because it lives Windows-side).
