Steps To Reproduce

1. Create a server using Bedrock Dedicated Server
2. Have about 30+ cows in a pen (8x8)
3. Hold wheat in your hands

Doing these steps will cause the cows to lag really bad (they stop walking and only take a step every few seconds)

Additional Info: 

• This only appears to affect the Linux version of BDS, the Windows version runs fine with the same world file
• I am currently the only user logged in to the server
• The server is in my home so it is running via LAN
• The CPU utilization of the server is less than 10% and the RAM utilization of BDS is less than 1GB
• Doing these steps with a local world does not have issues, it is only the BDS that is affected
• If you stop holding wheat, the cows no longer lag, it is only when you are holding wheat
