Question: how to improve the preformance?

[mehdisadeghi]

I spent sometime today and tried to use memoist to modify jekyll-tagging to cache some functions such as add_tag_cloud hoping that my website will build faster.

It has a limited number of posts (50) and it takes around 9 second to build on a Core i5 2.5GHz CPU with plenty of RAM. If I disable jekyll-tagging it builds in 2.5 seconds. So 6.5 seconds are spent for building the tag pages.

By profiling with ruby_prof I realized there are some expensive functions in the code. One such function is replace_diacritics, another one is add_tag_cloud and some time is spent for looping over sequences here and there. My memoizing efforts were fruitless.

So the question is how we can improve the build performance? I appreciate any ideas.
