Verified Benchmarks: JChat vs Legacy PHP Chat
Why modern real-time communities need true WebSockets on a $5 VPS instead of fragile shared-hosting polling scripts.
P99 via Persistent WebSockets
HTTP AJAX Polling Interval
Requests/sec on Bun + Elysia
Requests/sec on PHP 8 + FPM
Single Event Loop Process
PHP-FPM Worker Pool Exhaustion
In-memory Redis Stream Bus
Constant MySQL Polling Queries
HTTP API & Handshake Throughput
Requests per second under sustained load (wrk / autocannon)
11x faster than PHP 8.3
vs 1,400 MB PHP Pool
Instant native boot
Active socket headroom
WebSocket Latency Profile
Monitored on 1,000 concurrent sockets across 10 active rooms
Instant frame delivery
90% under 3.5ms
Near real-time tail
Guaranteed sub-10ms
Architectural Comparison: JChat vs Traditional PHP Chat
Understanding the real-world trade-offs between modern VPS-backed WebSockets and legacy shared-hosting polling scripts.
Hosting Target
Runs on any $4–$5/mo VPS (Hetzner, DigitalOcean, Linode) or containerized cloud.
Built for cheap shared hosts where long-running processes and background daemons are blocked.
Real-Time Protocol
Full-duplex instant socket with Redis pub/sub. Broadcasts reach all room members in under 10ms.
Client browser executes periodic HTTP GET requests every 1.5s to check for new messages in database.
Server Concurrency at Scale
Zero-allocation non-blocking event loop handles thousands of active connections simultaneously.
50 active users polling every second triggers CPU limits and '508 Resource Limit Reached' on shared hosts.
Database Impact While Chatting
Messages broadcast through an in-memory Redis stream. PostgreSQL is written asynchronously.
Every polling user runs 'SELECT ... WHERE id > last_id' continuously, causing row-lock contention.
Frontend & Design Architecture
Server-rendered progressive hydration, OKLCH perceptual tokens, RTL-native, and zero layout shift.
Legacy DOM manipulation, inline script tags, and synchronous server page reloads.
Extensibility & Plugins
Capability-based permission model. Addons execute in isolated sandboxes without modifying core files.
Custom features require manually editing vendor PHP and SQL files, breaking upgrade compatibility.
