Why TCP BDP Is the Hidden Killer of Network Latency

The article explains the concept of Bandwidth‑Delay Product (BDP), why an undersized TCP window throttles high‑bandwidth links, and provides step‑by‑step diagnostics, scripts, and practical Linux tuning methods—including window scaling, congestion‑control selection, and real‑world case studies—to eliminate BDP‑related performance bottlenecks.

Why Does Database Master‑Slave Replication Lag Every Day at 5‑7 AM?

The article investigates why master‑slave replication delay spikes each morning between 05:00 and 07:00, tracing it to the inventory‑snapshot worker that floods binlog traffic, evaluates five mitigation strategies, implements a big‑data extraction pipeline to Elasticsearch, and reports that the nightly delay disappeared and disk utilization improved.
