Yeah, not really a fan of this. What are you measuring in the screen shot? Would it make sense to reduce the initial size of the ArrayDeque? |

@chrisvest allocations, for some of our envs, the main problem is GC. We can easily scale CPUs, but when we reach a certain level of allocations, more CPUs won't help. So right now we're aggressively reducing allocations in our own code, netty and other 3-d parties.
Yeap. It will help partially. I think it can be safely decreased 2 times, maybe even 4. |

I'm fine with this change. But can you add some tests? In particular for the transitions to the queue |

Motivation: `HttpServerCodec` always allocates an `ArrayDeque`. However, the code inside needs only 2 actual headers: HEAD, CONNECT. So we can pack that as 2 bits within long field, to avoid `ArrayDeque` allocation + fallback for `ArrayDeque`, which is unlikely to happen with typical workloads. <img width="381" height="62" alt="image" src="https://github.com/user-attachments/assets/0bfe1501-4138-4223-abba-2630c5fd938b" /> Modification: Introduce `long methodQueue`, which we use as a queue to pack 2 bits for every incoming request + fallback to `ArrayQueue`, when `long methodQueue` is overflowed. Result: No more `ArrayQueue` allocation when a new pipeline is built with `HttpServerCodec`. P. S. It complicates code and maintenance, so feel free to close if you think it's not worth it. As it's easy to introduce our own fixed version. (cherry picked from commit 92117fe)

Motivation:
HttpServerCodecalways allocates anArrayDeque. However, the code inside needs only 2 actual headers: HEAD, CONNECT. So we can pack that as 2 bits within long field, to avoidArrayDequeallocation + fallback forArrayDeque, which is unlikely to happen with typical workloads.Modification:
Introduce
long methodQueue, which we use as a queue to pack 2 bits for every incoming request + fallback toArrayQueue, whenlong methodQueueis overflowed.Result:
No more
ArrayQueueallocation when a new pipeline is built withHttpServerCodec.P. S. It complicates code and maintenance, so feel free to close if you think it's not worth it. As it's easy to introduce our own fixed version.
