Performance Test Reports

Do you have a performance test report or a testimonial you want to post here? Please contact us either publicly or privately.

Unlike usual expectations, NIO frameworks have different performance characteristics in spite of the fact that they are using the same NIO selector provider. What's observed is that the difference comes from the fundamental factors such as the right choice of data structures and proper thread contention management, and those factors should never be overlooked. Netty has succeeded to introduce the breakthrough in NIO framework performance with careful engineering, while retaining the flexible architecture.

Please find out the excellence of Netty in performance from the following test reports:

Testimonial

Netty proved instrumental in the architecture of a replacement of an existing high-speed server that parses and caches live streaming quotes. Under stress tests, the new server could parse and store in excess of 260,000 quotes/sec, a figure not remotely possible with blocking I/O. Netty's well-documented API, excellent examples and first-class support made development a pleasure and unlocked the power of Java NIO. It is, hands-down, my first choice for a networking library.
