Here is my logstash.yml:

> config.reload.automatic: true  
> dead\_letter\_queue.enable: true  
> http.host: 0.0.0.0  
> path.config: /home/logstash\_user/logstash/conf.d/  
> path.logs: /var/log/logstash  
> pipeline.batch.size: 250  
> pipeline.workers: 8  
> queue.checkpoint.writes: 1  
> queue.type: persisted

And this is the directory of the persistent queue:

> $ sudo ls -lah /home/logstash\_user/logstash/data/queue/main/  
> total 12M  
> drwxr-xr-x 2 naas\_logstash logstash\_user 80 Feb 27 15:12 .  
> drwxr-xr-x 3 naas\_logstash logstash\_user 18 Feb 22 11:52 ..  
> -rw-r--r-- 1 naas\_logstash logstash\_user 34 Feb 27 15:12 checkpoint.head  
> -rw-r--r-- 1 naas\_logstash logstash\_user 0 Feb 22 11:52 .lock  
> -rw-r--r-- 1 naas\_logstash logstash\_user 64M Feb 27 15:12 page.862  
> -rw-r--r-- 1 naas\_logstash logstash\_user 4 Feb 22 11:52 .queue-version

It's using the default max page size of 64M and the default total queue size of 1GB. However, the queue never creates a tail page and only ever keeps the head page filled. I'm seeing slowness in processing input messages so shouldn't it be using the whole queue? Thank you!
