<ul><li>The peek method allows you to inspect each element in the pipeline without altering the stream.</li><li>Break down the pipeline into smaller parts for better visibility.</li><li>Integrate logging into your stream operations to monitor the flow of data.</li><li>Parallel streams can speed up computation for large datasets by leveraging multiple CPU cores.</li><li>Combine operations where possible to avoid excessive intermediate operations.</li><li>Stateful operations like sorted and distinct can lead to memory overhead. Limit their use, especially on large datasets.</li><li>Utilize specialized streams (IntStream, LongStream, DoubleStream) for numerical data to avoid boxing and unboxing overhead.</li><li>Use short-circuiting operations like limit and findFirst to terminate pipelines as soon as possible.</li></ul>
