Motivation: HttpMethod#valueOf shows up on profiler results in the top set of results. Since it is a relatively simple operation it can be improved in isolation. Modifications: - Introduce a special case map which assigns each HttpMethod to a unique index in an array and provides constant time lookup from a hash code algorithm. When the bucket is matched we can then directly do equality comparison instead of potentially following a linked structure when HashMap has hash collisions. Result: ~10% improvement in benchmark results for HttpMethod#valueOf Benchmark Mode Cnt Score Error Units HttpMethodMapBenchmark.newMapKnownMethods thrpt 16 31.831 ± 0.928 ops/us HttpMethodMapBenchmark.newMapMixMethods thrpt 16 25.568 ± 0.400 ops/us HttpMethodMapBenchmark.newMapUnknownMethods thrpt 16 51.413 ± 1.824 ops/us HttpMethodMapBenchmark.oldMapKnownMethods thrpt 16 29.226 ± 0.330 ops/us HttpMethodMapBenchmark.oldMapMixMethods thrpt 16 21.073 ± 0.247 ops/us HttpMethodMapBenchmark.oldMapUnknownMethods thrpt 16 49.081 ± 0.577 ops/us |

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
