Json.net Schema IsValid slow

I have a web service that interacts with the client with JSON messages, the runtime itself is not aware of the data model, so I am using the json.net schema to validate messages from the client and within the service itself, however This leads to a lot of overhead with performance point of view.

Simplified code that still contains enough context to understand what I am doing.

public class Template
{
    /// <summary>
    /// Template known as
    /// </summary>
    public string Name { get; private set; }
    /// <summary>
    /// Razor Template
    /// </summary>
    public string RazorTemplate { get; private set; }
    /// <summary>
    /// Json Schema definition
    /// </summary>
    public string Schema { get; private set; }

    private JSchema _schema { get; set; }

    private JSchema JSchema
    {
        get
        {
            if (_schema == null)
                _schema = JShema.Parse(Schema);

            return _schema;
        }
    }

    private void Validate(JObject obj)
    {
        // Schema validation Error messages.
        IList<string> ValidationError;

        // Schema validation.
        if (!obj.IsValid(JSchema, out ValidationError))
        {
            throw new Exception(string.Join(",", ValidationError.ToArray()));
        }
    }


    public string RunTemplate(JObject jobj)
    {
        // Validate Json Object. 
        Validate(jobj);

        // Code here that access our RazorEngine cache, and add then run Razor Template, or directly run a cached Razor Template...

        return "Here we return string generated by RazorEngine to sender.";
    }
}

      

        
        
        
      

    

Let's say I'm running a simple "Hello @ Model.Name!" a template that checks that the json has a Name string, this will be 15-20 times slower than if I fully commented out the check.

Are there better ways to use IsValid in a Json.Net schema?
