During a recent team offsite, the Engineering team focused on improving Filebeat's performance by analyzing memory allocation using pprof profiles, particularly during specific logging scenarios. The investigation centered on the event hot-path to identify memory inefficiencies, which revealed that a significant amount of memory was allocated during event processing, specifically due to the logp.newLogger function that instantiated a new logger for each log event, consuming 9.2GB of memory. By removing the unnecessary logger, the team successfully reduced memory usage from 109GB to 99GB for their benchmark, demonstrating a notable optimization. This improvement is part of ongoing efforts by Elastic's Platform Ingest team to enhance performance, with more updates expected in the future.
