Web Service Performance Tuning Tips

Tip 1#     Use coarse grained web services with moderate size payloads

Tip 2#     Choose correct service (RPC or Document) and encoding (Encoded or Literal) style for web service

Tip 3#     Carefully design SOAP attachments and security implementations to minimize negative performance

Tip 4#     Achieve Web services interoperability

§         Web Service implementation in Java: Use primitive types, String or simple POJO as parameters and return type

Tip 5#     Opt for RESTful Web Services

§         Language and platform agnostic

§         Uses standard HTTP methods to access web services

§         Need better performance and scalability

§         Much simpler to develop than SOAP

§         Small learning curve, less reliance on tools

§         Could be used when web services are not sophisticated and there is not need for QoS

Tip 6#     Consider using an asynchronous messaging model with

§         Slow and unreliable transport

§         For complex and long running process

Tip 7#     Use replication and caching of data to improve performance by minimizing network overhead

Tip 8#     Use XML compression where the XML compression overhead is less than network latency

Transmitting attachments such as MRI Scans, X-Rays, Design Documents and Business Contracts using SOAP messages has become a common practice.. Optimize transmission of attachments with MTOM & XOP:
