Am I having a serious memory leak problem?

Question

I am creating a Windows form application in C # that reads from hundreds of files and creates a hierarchy of objects. In particular:

DEBUG[14]: Imported 129 system/s, 6450 query/s, 6284293 document/s.

Amount is the total amount of the created object. Objects are really simple, by the way, only some int / string properties and strongly typed lists inside.

Question : Is it normal that my application consumes about 700 MB of memory (in debug mode)? What can I do to reduce memory usage?

EDIT : that is why I have 6284293 objects if you are just curious. Imagine a search engine called "system". There are more requests in the system.

public class System
{
  public List<Query> Queries;
}

Each request object refers to a "topic"; this is the main argument (for example, the search for "Italian weekend"). This is a list of the extracted document inside:

public class Query
{
  public Topic Topic; // Maintain only a reference to the topic
  public List<RetrievedDocument> RetrievedDocuments;
  public System System; // Maintain only a reference to the system
}

Each received document has an assessment and rank and has a link to a topic document:

public class RetrievedDocument
{
  public string Id;
  public int Rank;
  public double Score;
  public Document Document;
}

Each topic has a set of documents inside that may be relevant or not relevant, and a link to its parent topic:

public class Topic
{
  public int Id;
  public List<Document> Documents;
  public List<Document> RelevantDocuments
  {
    get {return Documents.Where(d => d.IsRelevant());}
  }
}

public class Document
{
  public string Id;
  public bool IsRelevant;
  public Topic Topic; // Maintain only a reference to the topic
}

There are 129 systems, 50 main topics (129 * 50 = 6450 objects of the request), each request has a different number of documents extracted, a total of 6284293. I need this hierarchy to perform some calculations (average accuracy, topic facilitation, average system accuracy, relevance) . Here's how TREC works ...
