Vuepress building is too slow ?!

• I confirm that this is an issue rather than a question.

Bug report

My project is large, it maybe contain 6000 markdown files. Once, I meet the dev performance problem, and I solve it by this command node --max_old_space_size=8192 ./node_modules/vuepress/cli.js dev src.

But, when I run building production, the process is too slow. I also modify the building command with node --max_old_space_size=8192 ./node_modules/vuepress/cli.js build src. Unfortunately, it doesn’t work.

Version

“vuepress”: “^1.0.0-alpha.47”,

@ulivz I wouldn’t wipe this issue out so quickly. Sure @JimmyVV should provide more data but I’m migrating a documentation (5000+ files) from Metalsmith to VuePress and the main issue we have now is that we can’t deploy on Netlify because the build time is longer than the maximum build timeout. Metalsmith did build the whole doc within Netlify’s timeouts.

Ok, Vuepress’ build process is surely more complex than Metalsmith and Vuepress is indeed a better tool, but yet… The build time is incredibly bigger in VP and this is strange.

So this is meant to add some data to the “comparison with other static website building tools” you asked above, @ulivz .

@JimmyVV please, would you post your investigations about memleaks introduced by the default theme?

Another point that cannot be ignored is that when @JimmyVV downgrades, the perfs are better. I definitely think we should look into this.

Recently, I used node workers to speed up the compiling process. the total time decrease from 10min to 2min. Maybe this is another way to improve the compiling procedure, by worker thread.
