Consider to speed up the generating process

[Liam0205]

I agree and want to create new issue

• Yes, I was on Hexo Docs page, especially on Templates, Variables, Helpers and Troubleshooting.
• Yes, I was on NexT Documentation Site.
• And yes, I already searched for current issues and this is not help to me.

---

Expected behavior

When I was using old version of NexT (0.x), generating 250+ posts costs around 1.4 minutes. I consider this is the expected behavior of Hexo generating speed.

Actual behavior

Now, generating 280 posts cost more than 7 minutes, and one day it costs me 20 minutes, which is not considered to be tolerated.

Steps to reproduce the behavior

$ hexo clean && time hexo generate

• Link to demo site with this feature: N/A
• Link(s) to source code or any usefull link(s): N/A

What I've tried

Here are what I've tried:

• specify programming language for code blocks in all posts, based on this post and this post.
• enable NexT's cache, introduced in version 6.0.0, based on Hexo theme NexT generate too much slower than default theme (landscape) #539 (comment).

NexT Scheme:

• All schemes
• Muse
• Mist
• Pisces
• Gemini

Hexo's and NexT's version number, configuration of Hexo and NexT, and environment information could be found in #658 .

Test for cache-disabled. disable_cache.log

$ hexo clean && time hexo generate > disable_cache.log 2>&1
INFO  Deleted database.
INFO  Deleted public folder.

Test for cache-enabled. (didn't get the announced 3x speed-up.)
enable_cache.log

$ hexo clean && time hexo generate > enable_cache.log 2>&1
INFO  Deleted database.

Same issue in all schemes.
See https://hexo.io/docs/templates.html#Optimization.
Fragment Caching may be a good way, but it takes a lot of work.

Same issue in all schemes.

Scheme or theme? Is this a NexT specific problem? --- based on #539 , it seems to be.

Do your team has a plan for this?

@Liam0205 issue will be fixed soon. I've already turnkey solution, need just to debug it.

[Liam0205]

@ivan-nginx Glad to know!

If there is any progress of it, or if any test task needed, please let me know.

I think use partial helper instead of include swig tag may be improved to some extent.

partial read data from theme.views object.

include read from disk file.
