Describe the bug

While using Vite for bundling large codebase (around 700 files served) on Windows machine (reproducible both on windows 10 and 11 beta) Vite page load time takes around 5-30 seconds depending on drive type (NVME on-board SSD, NVME SSD, SATA SSD), comparing to <2 seconds on Mac (did not try on linux).

Core reason is tryFsResolve function

Which is using accessSync call, which is internally using multiple sync FS calls, and NTFS (specifically NTFS, looks like FAT is working better) is rather complex system with multiple checks that can take milliseconds; also this is causing the server act in sync mode (instead of async) and not utilize the benefits of parallel http requests.

Another reason is rather slow HTTP service which takes several seconds overhead; I was able to win few seconds with page with this script (https://gist.github.com/Jabher/c9e5f9bb905c8ec2ab6289a181c2b6ce). Probably switching from express to fastify or native code will make things work faster.

Reproduction

issue seems obvious as long as performance result like was provided and specific code part was targeted as a reason of bug
