What is CI4 vs Laravel performance comparison?

Performance comparison between CI4 and Laravel depends on the use case. CI4 has lower framework overhead: fewer service providers, simpler DI, and a lighter bootstrap process result in faster cold start times and lower memory consumption per request. Benchmarks show CI4 handling ~20-30% more requests per second than Laravel in simple scenarios. However, absolute performance differences are usually dwarfed by I/O (database queries, network calls) in real applications. Laravel compensates with Octane (eliminates bootstrap cost entirely by keeping the app in memory) and OPcache. For raw throughput, both frameworks perform well enough for typical web applications. Choose based on features, ecosystem, and team expertise rather than benchmarks. For genuinely high-performance scenarios (100k+ RPS), both may need to offload work to queues, add caching layers, and optimize database access — the framework choice matters less than the architecture.
