Architecting Modern Java EE Applications

Performance

Traditional logging, especially extensively used logging invocations, creates a lot of string objects. Even APIs such as Slf4J that aim to reduce unnecessary string concatenation will result in high memory rates. All these objects need to be garbage collected after their use, which utilizes the CPU.

Storing log events as string messages is a verbose way of storing information. Choosing different formats, mainly binary formats would drastically reduce the message size and result in more efficient memory consumption and higher throughput.

Log messages that are stored in a buffer or directly on disk need to be synchronized with other log invocations. Synchronous loggers ultimately cause a file to be written within a single invocation. ...
