Are Node.js + Express.js or Meteor good options for a Real Estate Website

[Miguel Vasquez]

First of all sorry for my English, I am using online translators, I hope you understand my question.  I am newbie to web development but I have some experience with C# developing desktop applications and need advice. I will going to enter in the Real Estate Business and I want to develop my Real Estate WebSite by myself. I'm right now learning HTML, CSS and Javascript and I need to know if the Meteor framework or Node.js are optimal choices for a Real Estate site that I hope will have high traffic or Django/Python  is a better option to develop a Full Featured and fast performance Real Estate Website.  For example if my site is visited for 15,000 visitors at the same time and 5,000 of these visitors use the search box at the same time to filter the properties by location, price, etc, which of this three, Django or Meteor or Node.js is better suited to handle the concurrency in this particular user action with less waiting time for the visitors in show the results from the search.  In other words, Is the Non-Blocking I/O ability and built-in support for Concurrency of Meteor or Node.js an advantage in performance in a high concurrency scenario where multiple users visit my website and request information from the database at the same time, or is not an advantage for this scenario. 

I ask this question because i want to make my visitors happy with Ultra-fast speed to show the search results and Ultra-fast speed in Page Loading Times.

A last detail to mention is that I will not use Photos of the properties listed in my website, I will use only embedded YouTube videos from my YouTube Channel ( No need to hosting the videos) of the Houses or Apartments with the respective information about them in the space below the embedded video.

Sorry for my newbie questions and for repeat certain details several times, but i need to choose the right tool for the job in order to not loose my learning time and in the future have to rewrite my entirely website to other Development platform.

thanks in advance,
best regards
