I would like to know whether there is a specific parameter that should be configured in order to have higher throughput while performing CSV export from the graylog GUI.
When I try to retrieve the records on the elasticsearch side it is returned quite quickly, but when I do it the graylog way, the download rate is less than 5% compared to when I was using version 2.3.1
Since the community was so responsive, I will answer my own question.
The problem was that I had the -Djavax.net.debug=all enabled in /etc/default/graylog-server. After removing the debug option, everything works as expected.
