FPS drops when there's an online raid

I use this plugin to reward online raids on my server by providing protection to players when they're offline. The problem is that now, when they're in an online raid, the server's FPS drops drastically, making it completely unplayable. The last time I checked, it dropped to 3 FPS, and I had to turn off the plugin for the server to run smoothly. The server ran perfectly after I did this, but when I tried again a few days later, the exact same thing happened. I'm going to send you the screenshot of what happened in Grafana with your plugin.

I really like the plugin and your idea, but I think its performance isn't what I expected. If this is fixed, I definitely want your plugin.

Where they using fire rockets in the raid?

because i had last wipe same problem and it happend only when they where using fire rockets

but that whas before the last update of raid protection

This happens with any type of damage, not just with fire missiles.
