 While profiling WordPress with [https://blackfire.io Blackfire] we found
 that parsing an ''mo'' file is a heavy task, and it's done on each page.

 We propose to use the Object Cache API to not re-parse the file if it
 hasn't changed.
 This way any non English installations with a plugin implementing the
 Object Cache API could benefit of a significant performance improvement.

 You can see here a comparison showing the performance improvement:

 We found that a few plugins are doing the same thing but they are used
 very much and we think it could be great to have it mainstream.
