What can be expected from the performance of REST compared to SOAP?

• A. REST is inherently slower due to its architecture
• B. REST handles stateful communication better than SOAP
• C. REST is generally faster and more efficient
• D. REST requires more resources than SOAP

Answer: (C)

The expected performance attributes of REST compared to SOAP indeed highlight that REST is generally faster and more efficient. This is largely due to REST's lightweight architecture, which typically relies on standard HTTP protocols. Since REST uses stateless communications and a simpler messaging format, it incurs less overhead than SOAP, which invokes additional complexity through its use of XML and WSDL. REST's statelessness also allows for easier scaling, as each request from the client to the server contains all the information needed to understand and process the request. This means that the server does not need to retain information about client sessions, leading to faster processing times and reduced server resource consumption under high load. Moreover, the use of multiple formats like JSON, which is more compact than XML, further enhances the performance and efficiency of RESTful services. This resource-efficient approach makes REST a preferred choice for web services that demand high performance and lower latency, particularly in modern web applications and mobile services.
