I am storing the huge dataset in the session variable. which is causing the performance of the application. As the dataset has the information which is specific to the user hence cannot store this huge data in cache object.
Now I am converting this dataset into xml and storing into the session as a string. While retrieving the data I am again converting that xml string into dataset.
will this move help me to improve the performance of the application?
What are other options to reduce the size of the user session and improve performance of the application.

What I have tried:

// Convert dataset to string and storing in the session
Session["UserData"] = Ds.GetXml().ToString();

// Convert string to dataset
   DataSet DS = new DataSet() ;
   stream = new StringReader(xmlData);
   reader = new XmlTextReader(stream);

What do you mean by "huge"? How much and what kind of data are you talking about?

There are problems with using the Session object.

It is around 194KB per session but when multiple request threads at same instance than it consumes high cpu cycle and slow down the application. I am storing dataset as data in session.

Converting it to string is going to take even more space in the session and the converting to string then back to data is also going to take CPU time so it'll probably end up in worse performance and more memory usage. Leave it as a DataSet, or better still see if you can just not store so much data per person. You never know, reading the data from a database only when you need it might not be so bad in terms of performance.

Generally not using XML will improve performance, try using fastJSON[^] for dataset serialization.

Not holding onto "huge" data will be the better way.

Try rethinking what you really need to store, other than the above we cannot help you with the little information you have provided.

After converting dataset to json and storing it in the session variable will it help to improve the performance?
