After I upgraded from graylog version 2.2.1 to 2.4.3, the csv export became quite slow compared to the previous download rate. I have to say that I did many changes
- putting it behind pfsense
- using readonlyrest to restrict access and change to secure communication
- Switching communication to private ips only
I really can't reproduce the problem, as I tried sniffing using Wireshark and tcpdump which both didn't show any irregularities.
Any guidance on how to proceed with debugging this problem is much appreciated.
