Cache Aggressively - -```php -// Good: 1-second TTL (99% hit rate) -$cache->save($key, $value, 1); - -// Bad: No caching -$value = $db->query(...); -``` - -### 3. Use Coroutines - -```php -// Good: Non-blocking I/O -Coroutine::create(function () { - $client->get('/api'); -}); - -// Bad: Blocking I/O -file_get_contents('http://api.example.com'); -``` - -### 4. Monitor Everything - -```php -// Add timing to all operations -$start = microtime(true); -$result = $operation(); -$latency = (microtime(true) - $start) * 1000; - -// Log slow operations -if ($latency > 100) { - echo "Slow operation: {$latency}ms\n"; -} -``` - -## 📈 Performance Optimization Checklist - -- [x] System limits configured (file descriptors, sockets) -- [x] Swoole optimizations enabled (TCP fast open, CPU affinity) -- [x] Connection pooling implemented -- [x] Aggressive caching (1-second TTL) -- [x] Shared memory tables for hot data -- [x] Coroutines for async I/O -- [x] Zero-copy forwarding where possible -- [x] Monitoring and metrics exposed -- [x] Load testing completed -- [x] Bottlenecks identified and fixed - -## 🏆 Performance Results - -### HTTP Proxy - -``` -Total requests: 1,000,000 -Total time: 3.57s -Throughput: 280,112 req/s -Errors: 0 (0.00%) - -Latency: - Min: 0.21ms - Avg: 0.68ms - p50: 0.71ms - p95: 1.23ms - p99: 3.15ms - Max: 12.34ms - -Cache hit rate: 99.82% -``` - -### TCP Proxy - -``` -Total connections: 100,000 -Total time: 0.79s -Connections/sec: 126,582 -Errors: 0 (0.00%) - -Latency: - Min: 0.12ms - Avg: 0.45ms - p50: 0.42ms - p95: 0.89ms - p99: 1.67ms - Max: 5.23ms - -Throughput: 12.3 GB/s -``` - -### SMTP Proxy - -``` -Total messages: 100,000 -Total time: 1.61s -Messages/sec: 62,111 -Errors: 0 (0.00%) - -Latency: - Min: 0.34ms - Avg: 1.12ms - p50: 1.05ms - p95: 2.34ms - p99: 4.12ms - Max: 15.67ms -``` - -## 🎓 Further Reading - -- [Swoole Performance Tuning](https://wiki.swoole.com/#/learn?id=performance-tuning) -- [Linux Network Tuning](https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt) -- [Redis Performance](https://redis.io/docs/management/optimization/) -- [Database Connection Pooling](https://www.postgresql.org/docs/current/pgpool.html) From 27d1e9e03ee8bc22a4ccd5b073ebc9a5e1fed437 Mon Sep 17 00:00:00 2001 From: Jake Barnby Date: Thu, 12 Mar 2026 23:14:25 +1300 Subject: [PATCH 43/80] (docs): Update README to match current codebase --- README.md | 400 ++++++++++++++++++++++++++++++++++++------------------ 1 file changed, 271 insertions(+), 129 deletions(-) diff --git a/README.md b/README.md index 4436c96..4afa8cf 100644 --- a/README.md +++ b/README.md @@ -23,9 +23,9 @@ High-performance, protocol-agnostic proxy built on Swoole for blazing fast conne | CPU utilization at peak | ~60% | Memory is the primary constraint.
