Benchmarks
Comparison between local PHP Atomic semaphore and distributed Go + Redis/Lua semaphore.
| Metric | PHP Atomic (local) | Go Distributed (Redis+Lua) |
|---|---|---|
| Total time (1000 iterations) | 0.51 ms | 382.96 ms |
| Average per operation | 0.51 µs | 382.96 µs |
| Performance ratio | 1x | 757x slower |
- PHP Atomic is ultra-fast (nanoseconds) but works only on a single node.
- Go Distributed is slower due to network calls, but enables synchronization across multiple servers.
Choose based on your architecture: local semaphore for a single pod, distributed for a cluster.
