5 years ago Minecraft 1.14.x itself has major issues, mainly related to performance but also some related to data stability / crashing / etc. Citizens is not the cause but rather a victim of these issues.
If you want a stable server, use 1.13.2 or 1.12.2.
To best track down performance issues, you need a Java Profiler like Spark to get a proper analysis.
Versions: This server is running Paper version git-Paper-210 (MC: 1.14.4) (Implementing API version 1.14.4-R0.1-SNAPSHOT) Citzens: Citizens (2.0.25-SNAPSHOT (build 1762) (save file: https://pastebin.com/kZ4kKuTF )
After upgrading our paper spigot server to 1.14.4 we expect massive performance issue because of Citizens2. We tested this and it took us 1 day to find out that the issue is Citizens.
To see what happens you need to turn on debug (/debug start) on the server. Then you see something like this: https://hastebin.com/mabezimuga.shell
The more NPCs you have the more debug messages are spammed into console and the higher the TPS drop is.
I hope this is enough information for you to get this issue fixed. If not, let me know, I can provide further information.
