Boosting speed: Use eBPF and netstacklat to troubleshoot latency

This blog post explores network latency issues in applications and introduces 'netstacklat', a monitoring tool leveraging eBPF to measure latency within the Linux network stack. It highlights the importance of diagnosing local host latency and provides a detailed example of using netstacklat to improve the performance of a high-load Nginx server setup. The blog details how inaccurate latency observations can lead to underperformance and discusses appropriate configurations and tests to optimize server response times.
