What's Changed

  • libuv bumped to 1.52.1 — versions below 1.52.1 have known IO-URING issues on Linux; all UNIX/Linux builds and Docker images now ship with the fixed version.
  • OPcache production config in Docker images — both php-true-async (Debian) and FrankenPHP images now ship with a tuned opcache.ini out of the box: JIT tracing mode, validate_timestamps=0 (files don't change in containers), 256 MB bytecode cache, 128 MB JIT buffer.

Performance Benchmarks

We ran a realistic benchmark against Laravel + PostgreSQL (10 SQL queries per request, 1000 req/s constant load, 30s duration) comparing TrueAsync against Swoole NTS, Swoole ZTS, and FrankenPHP Octane.

Throughput (16 workers)

Server req/s vs TrueAsync Dropped requests
TrueAsync 993 req/s — 1.1%
Swoole NTS 599 req/s TrueAsync +66% ~38%
Swoole ZTS 601 req/s TrueAsync +65% ~36%
FrankenPHP Octane 556 req/s TrueAsync +79% ~41%

TrueAsync handles the full target load with just 4 workers. Blocking servers need ~25 workers to reach the same throughput — a 6× worker efficiency advantage.

Latency at 4 workers

Server P50 P95
TrueAsync 28 ms 60 ms
Swoole NTS 5,440 ms 5,630 ms
Swoole ZTS 5,320 ms 5,520 ms
FrankenPHP Octane 5,240 ms 5,390 ms

The entire difference is queue wait: with 4 blocking workers at 1000 req/s, requests sit in queue for ~5,400 ms. TrueAsync coroutines handle requests immediately — queue wait is ~0 ms.

Memory footprint (idle)

Server 4 workers 16 workers
TrueAsync 147 MB 326 MB
Swoole NTS 481 MB (+227%, 3.3×) 762 MB (+134%, 2.3×)
Swoole ZTS 512 MB (+248%, 3.5×) 765 MB (+135%, 2.3×)
FrankenPHP Octane 357 MB (+143%, 2.4×) 421 MB (+29%, 1.3×)

Each Swoole worker bootstraps its own full copy of the Laravel application (~22 MB/worker). TrueAsync coroutines share the bootstrap within a single worker — ~2.5 MB per coroutine, ~89% less than Swoole (9× lighter).
