Brian Clozel	31a62ff8ba	Add JMH benchmarks for Protobuf message converter This commit re-generates the protobuf Java classes with a recent version of the protoc binary and adds JMH benchmarks that exercise the message converter for both the reading and writing cases. See gh-29496	2 years ago
Brian Clozel	61d893257e	Rewrite "performance" test to JMH benchmarks This commit rewrites the remaining "fastEnough" performance tests into proper JMH benchmarks. See gh-24830	5 years ago
Rossen Stoyanchev	683cc2eb7f	Add NDJSON and deprecate application/stream+json Closes gh-21283	5 years ago
Brian Clozel	567265123b	Avoid using regex matching for static patterns Prior to this commit (and the previous one), the `AntPathStringMatcher` (inner class of `AntPathmatcher`) would compile `Pattern` instances and use regex matching even for static patterns such as `"/home"`. This change introduces a shortcut in the string matcher algorithm to skip the `Pattern` creation and uses `String` equality instead. Static patterns are quite common in applications and this change can bring performance improvements, depending on the mix of patterns configured in the web application. In benchmarks (added with this commit), we're seeing +20% throughput and -40% allocation. This of course can vary depending on the number of static patterns configured in the application. Closes gh-24887	6 years ago
Brian Clozel	612a63c0f1	Optimize MediaType parsing Prior to this commit, `MediaType.parseMediaType` would already rely on the internal LRU cache in `MimeTypeUtils` for better performance. With that optimization, the parsing of raw media types is skipped for cached elements. But still, `MediaType.parseMediaType` would first get a cached `MimeType` instance from that cache and then instantiate a `new MediaType(type, subtype, parameters)`. This constructor not only replays the `MimeType` checks on type/subtyme tokens and parameters, but it also performs `MediaType`-specific checks on parameters. Such checks are not required, as we're using an existing `MimeType` instance in the first place. This commit adds a new protected copy constructor (skipping checks) in `MimeType` and uses it in `MediaType.parseMediaType` as a result. This yields interesting performance improvements, with +400% throughput and -40% allocation/call in benchmarks. This commit also introduces a new JMH benchmark for future optimization work. Closes gh-24769	6 years ago
