Two macOS timeout primitives treated an absolute deadline as a relative countdown, silently turning bounded waits into infinite hangs under contention — the root cause of intermittent 30-second teardown stalls. Now fixed and soak-validated.
The psytest suite was rebuilt into a context-chained set of stages exercising context switching, time sync, guaranteed & best-effort messaging, signals, and catalog retrieval — each stage emitting a PASS/FAIL + perf line with a final aggregated verdict. It now reports full p50/p90/p95/p99/p99.9 tail-latency percentiles, not just averages.
We’re excited to release Psyclone AIOS 2.1.1 — the most significant update to Psyclone since the 2.0 line. If you build real-time, distributed, publish/subscribe systems, this release makes Psyclone faster, more portable, and far easier to drive from the language you already use. Here’s what’s new since our last release (2.0.3). Psyclone now runs natively…
We have today released the final version of the Psyclone platform, now officially out of Beta. Please visit the download page and grab either the source code or the binary release. Work will continue on Psyclone beyond the end of the project and we will keep this page updated with new versions.
The same socket-mode and buffered-read optimisations lifted best-effort UDP messaging to 155,000 messages/second (up from ~107k) with latency down to about 6 microseconds (from 9.3us) — reinforcing Psyclone’s sub-10us real-time profile.
The SSL build now links OpenSSL 3 and ships a network_https unit test that performs a real TLS handshake and encrypted HTTP round-trips over loopback with a runtime-generated certificate — with a clear certificate-verification hardening path on the roadmap.
By keeping sockets non-blocking instead of flipping mode around every send (which cost four syscalls per message and raced the receive thread), TCP throughput more than doubled — from ~42k to ~90k msg/s — and per-message latency roughly halved, from 23.8us to ~11us.
