With web projects, it is important to reduce file size to speed up how files are transmitted and received over the internet. This helps reduce the overall page load time and results in happier customers. To improve the load performance of your web applications, enable the Windows Dynamic Content Compression feature. This will reduce the data’s size, thus increasing the response time from the user’s perspective. The need for data compression also applies to client/server applications, especially if the file and data sizes that are being transmitted are huge.

Employ caching to improve network performance. Caching will store resources locally or keep them in memory for a certain period. Should such resources be requested again, then the locally stored resources will be checked and used instead of the network resources. This increases the access and load times of resources, and it also reduces network traffic. Cached resources will be updated if the resources have been updated, if the cache period has expired, or if the user has cleared their cache.

The two most common data transfer mechanisms are XML and JSON. These are text files that store structured information. Parsers are required to extract information from such files so that the extracted data can be utilized in the applications. But not all XML and JSON parsers perform the same. It would be prudent to benchmark the performance of various XML and JSON parsers to help you choose the most efficient and performant one for your data processing needs.

When you’re serializing and deserializing data, your objects and their hierarchies should match your JSON and XML formats so that processing is much faster.

Microsoft recommends that developers shouldn't use BinaryFormatter for transferring binary data as it is unsafe and can lead to denial-of-service (DOS) attacks. .NET offers several in-box serializers that can handle untrusted data safely:

XmlSerializer and DataContractSerializer can serialize object graphs into and from XML. Do not confuse DataContractSerializer with NetDataContractSerializer.

BinaryReader and BinaryWriter for XML and JSON.

The System.Text.Json APIs can serialize object graphs into JSON.
