ASP.NET MVC application takes up much more RAM on server than localhost

I have a problem.

My ASP.NET MVC project takes 9MB of RAM on localhost (tested in ant's profile) but when hosted (on server) it takes about 400MB on load. Then about 150MB of RAM. Why omg? This is one page. www.algoritmem.cz

I am using entity structure to connect to MSSQL 2014 database. The database is empty. No data. Just tables.
