zengzuo613 opened a new issue, #3375: URL: https://github.com/apache/logging-log4j2/issues/3375
I reviewed [the garbagefree documentation](https://logging.apache.org/log4j/2.x/manual/garbagefree.html), and it states that the Garbage-free mode requires additional configuration and activation. However, when I tested the [logback-perf](https://github.com/ceki/logback-perf) code, I noticed that even with the default configuration and extensive logging output, it did not trigger any GC (Garbage Collection). **perf result** ```bash Benchmark Mode Cnt Score Error Units AsyncWithFileAppenderBenchmark.log4j2AsyncFile thrpt 2 170.888 ops/ms AsyncWithFileAppenderBenchmark.log4j2AsyncFile:gc.alloc.rate thrpt 2 ≈ 10??
