🛡️ Wire Specification & RFC Conformance

Raw performance is only valuable when accompanied by rigorous protocol correctness and resilience against security vectors. Aegon undergoes continuous testing against the web ecosystem's gold-standard conformance suites:

Autobahn WebSocket Testsuite (RFC 6455)

• Score: 296 / 296 Passed (100% Clean Sweep)
• Validates the entire WebSocket specification: frame boundaries, opcode handling, reserved bits, fragmented control frames, UTF-8 code point validation, SWAR / SIMD unmasking correctness, close handshakes, and compression extensions.

h2spec (RFC 9113 / HTTP/2)

• Score: 145 Passed, 0 Failed (100% Clean)
• Strict verification of binary frame parsers, multiplexed stream state machines, flow control credit windows, HPACK dynamic table compression, SETTINGS negotiations, priority tree handling, and RST_STREAM resets.

Http11Probe (RFC 9110 / RFC 9112)

• Score: 158 / 159 Passed (99.4%)
• Exhaustively validates HTTP/1.1 message parsing, CRLF normalization, whitespace handling, header semantics, and full immunity against HTTP Request Smuggling (TE.CL, CL.TE, and dual-header ambiguities).

h3spec (RFC 9000 / RFC 9114 / HTTP/3 & QUIC)

• Score: 47 / 49 Passed (100% Core HTTP/3 & QPACK)
• Validates QUIC stream multiplexing, datagram encapsulation, HTTP/3 control and data frame state machines, and QPACK dynamic instruction encoding.

⚡ Cross-Platform Engine Benchmarks (io_uring, epoll, IOCP)

Aegon features a pluggable I/O engine architecture with zero-allocation stack awaiters. Below are comparative benchmarks executed on isolated physical CPU cores (Server on 2 dedicated cores; Client on 4 dedicated cores):

Protocol Suite	Workload	Linux io_uring (Kernel 6.1+)	Linux epoll	Windows IOCP (MSVC Native)	Windows Profile
HTTP/1.1 Plaintext	h2load/wrk -t4 -c100 -D10s	529,980 req/s (199 µs)	460,914 req/s (213 µs)	94,431 req/s (1.04 ms)	WinSock overlapped I/O
HTTP/1.1 TLS 1.3	h2load/wrk -t4 -c100 -D10s	398,164 req/s (248 µs)	358,038 req/s (273 µs)	86,655 req/s (1.14 ms)	91.8% of plaintext throughput
HTTP/2 Multiplexing	h2load -t4 -c100 -m10	1,392,360 req/s (656 µs)	1,324,911 req/s (728 µs)	355,548 req/s (2.42 ms)	3.76x multiplexing speedup
HTTP/3 (QUIC)	h2load --h3 -t4 -c50 -m10	875,254 req/s (570 µs)	876,920 req/s (573 µs)	283,238 req/s (1.62 ms)	0% packet loss (0 / 403k)

NOTE

• Linux: Leverages zero-syscall ring submission via io_uring and kernel-mapped buffer pools (PBUF_RING) for maximum throughput, with epoll providing seamless fallback on Docker and WSL2.
• Windows: Native Windows NT IOCP (GetQueuedCompletionStatusEx) delivers stable microsecond-range dispatch, zero packet loss under sustained QUIC load, and sub-3.8 ms p99 latencies.

🔬 Hardware Architecture & Why Aegon Leads

Aegon achieves these results through architectural innovations across kernel, CPU, and memory boundaries:

1. Linux io_uring Multishot Primitives

   • Zero-syscall request ingest via IORING_OP_RECV_MULTISHOT and direct socket registration via IORING_OP_ACCEPT_DIRECT.
   • Kernel-managed buffer rings (io_uring_buf_ring) provide zero-copy memory directly from NIC socket receive queues.

2. C++26 Symmetric-Transfer Coroutines

   • Eliminates coroutine call frame heap allocation on hot paths using symmetric transfer (std::coroutine_handle<>::resume()), achieving sub-microsecond latency.

3. Stepped SIMD Vector Acceleration

   • 4-tier vector fallback engine (AVX-512BW/VL → AVX2/BMI2 → SSE4.2 → Scalar) for instant case-insensitive header matching, URI parsing, and token extraction.
   • 5-tier SIMD / SWAR hardware unmasker for WebSocket frame payloads.

4. Zero-Allocation Protocol Engines

   • Contiguous response vector packing for pipelined HTTP/1.1.
   • Stack-allocated HPACK/QPACK buffer management for HTTP/2 and HTTP/3.
