I'm under attack (CPU goes up) - I will paypal donate to find a solution

Hello Otlanders,

Since more than a year I run an Otserver with 200+ online players.
If you are familiarized with Amazon Web Services, I Host the server in a r5.large instance (Ubuntu 18.04). It's RL Map, Tibia 11.9
Server characteristics:

• 2 vCPU of Intel Xeon Platinum 8000 series processor (Skylake-SP or Cascade Lake) with a sustained all core Turbo CPU clock speed of up to 3.1 GHz
• 16 GB RAM

I'm running an older version of the "OTX" project...
