How to Test

Try to build docs(about 1000 .md) by vuepess and vitepress

# first try vuepress
npm run build:vupress
# then try vitepress
npm run build:vitepress

1. You will see how much longer the Vuepress will take, in my Macbook Pro 2022 with M2
   In my Macbook Pro 2022 with M2, VuePress: 13mins+ vs VitePress：60-70s
2. Vuepress also use much much more memory then Vitepress
   It has to build with NODE_OPTIONS=--max_old_space_size=20480, otherwise node process will exit by JavaScript heap out of memory
