I have asked this question http://webcache.googleusercontent.com/search?q=cache:hVYasosVicoJ:superuser.com/questions/813721/what-are-the-biggest-bottlenecks-for-rendering-jpeg-images+&cd=1&hl=en&ct=clnk  
All I see now it is was deleted "for reasons of moderation".  
How can I see what were particularly those "reasons of moderation"?  
I've read faq about why would a question be deleted, but I can't find an explanation for my question.
