Performance Comparison of Logback and Log4j2 Synchronous vs Asynchronous Logging
This article revisits a previous logback configuration test, expands the sample size and repeats the measurements using JMeter, JProfile, and New Relic APM to compare synchronous and asynchronous logging in Logback and Log4j2, revealing that asynchronous logging reduces log latency but only marginally improves overall TPS, while Log4j2’s async implementation can boost TPS up to six times.
