Save on the first file get a little freeze time.

[luunguyenbk]

I'm using Atom 1.2.2 on Macos Yosermite, Atom-Beautify 0.28.19. When i first open Atom and save, it seem get a little freeze about 2-3 seconds, it only happen on the first file.
When i disable Atom-beautify, it don't happen anymore.
Is this a bug on Atom-Beautify ?

Here is the applicable code for beautify on save functionality: https://github.com/Glavin001/atom-beautify/blob/master/src/beautify.coffee#L423-L467

The part that would take time and could be causing the little freeze would be here: https://github.com/Glavin001/atom-beautify/blob/master/src/beautify.coffee#L427-L444

Since you indicated that it only happens on the first file, it would suggest that subsequent requests are using a cache and therefore faster. All of the require calls would be applicable then, since they have a built-in cache.

It could be because of the activationCommands: https://github.com/Glavin001/atom-beautify/blob/master/package.json#L105-L106
When you save, this triggers Atom Beautify to activate and thus require all of its dependencies. This could take time. After the first time, everything should be processed and cached.
This would make a lot of sense.

The best way to reduce the activation time and reduce the freeze time when first activating Atom Beautify would be to look at:

• https://github.com/Glavin001/atom-beautify/blob/master/src/beautify.coffee#L3-L13
• https://github.com/Glavin001/atom-beautify/blob/master/src/beautify.coffee#L464-L471

And try to cut things down.
I have not run any benchmarks however I presume that constructing the beautifier at https://github.com/Glavin001/atom-beautify/blob/master/src/beautify.coffee#L10 will take a significant amount of time on load.

Beautifiers = require("./beautifiers")
beautifier = new Beautifiers()

The main Beautifier code can be found at https://github.com/Glavin001/atom-beautify/blob/master/src/beautifiers/index.coffee
It probably has the most room for optimization and performance improvements.

This also affects "Installed Packages" page in preferences.

I'm going to count this issue as a duplicate of #876 as #876 has some more information that I can use for debugging.
Please continue discussion of this issue over at #876. Thank you.
