WSL2 makes Windows feel subtly slower and it's driving me crazy
Been running WSL2 daily for a while now, and I'm pretty convinced it quietly degrades the overall Windows experience. Nothing dramatic, nothing in Task Manager—just a bunch of small "huh, that's weird" moments that add up.
Setup: Windows 11 (latest stable), Ubuntu on WSL2, mirrored networking, decent hardware. Not a potato.
Stuff I keep noticing:
Wi-Fi list takes a second to populate. Instant when WSL is off.
Scrolling feels stuttery in random apps—Explorer, browsers, Settings.
Cursor drops frames occasionally. Not lag, just feels like frames are missing.
Sleep/wake is flaky—sometimes fine, sometimes forever, sometimes hard reset.
Touchpad acts up—gestures stop registering, occasional freezes, even a couple crashes I never had before.
Any single symptom you can shrug off as "eh, Windows being Windows." But shut WSL down and the machine feels noticeably snappier. Turn it back on, and within a day the hitches are back.
Not saying WSL2 is bad—it's incredibly useful. Just tired of the "zero overhead" narrative. There's a cost, it's just paid in small annoying increments instead of one obvious slowdown.
Curious if others have noticed the same.

Setting
networkingMode=host
and
dnsTunneling=false
in the WSL2 configuration file can significantly reduce network and system response latency.
If you notice the system becoming generally laggy after WSL2 has been running for a while, a full shutdown of WSL can help clear memory and system resources.
Every file operation has to cross a translation layer between the Linux and Windows file systems. For file-heavy workflows (like running git status, npm install, or using file watchers in webpack/Vite), this can make things 2x to 10x slower than when working from WSL2's native Linux filesystem.
