How to speed up Jekyll/Octopress generation?

Question

I'm using Octopress as my blog engine. It's perfect. But if there are many posts, for example 400+ posts, the speed of generation is soooo slow.

So, is there any way to speed up Jekyll/Octopress generation?

Thanks.

Answer 1

Obviously if you are just working on one post, there is no need to wait for the entire site to generate. What you are looking for is the rake isolate[partial_post_name] task.
Using rake isolate, you can “isolate” only that post you are working on and move all the others to the source/_stash folder. The partial_post_name parameter is just some words in the file name for the post. For example, if I want to isolate the post from the earlier example, I would use

rake isolate[plain-english]  

This will move all the other posts to source/_stash and only keep the 2011-09-29-just-type-the-title-of-the-post-here-in-plain-english.markdown post in source/_posts. You can also do this while you are running rake preview. It will just detect a massive change and only regenerate that one post from then on.
