Hi All, I am new to ElasticSearch and the ELK stack. I am using Logstash to parse my apache logs in addition to generating the fields using kv{} and sending the output to ES and I am using the default config. What happens is when I parse the first 15 log days which are nearly equivalent to 15 mil entry it works perfectly. However, when I add another 15 after the first finish it gets real real slow I dont know what might have caused that. I do have storage and I haven't changed the settings.

If you're using the default settings for ES then you should change some of them. Take a look at this chapter in the docs - > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

The most likely cause of your problems would likely be related to your heap size.
