Hello, Corey
It appears you have two issues, one with syncronizing the cluster, another with poor Latency. If you have an active Support Contract for those appliances, I would highly recommend to open an official Support Case. Any remote troubleshooting with no direct access to your system will take more time than needed. Regardless, you will most likely be able to resolve the Config Sync issue by yourself, please refer to this article to get you started with troubleshooting Config Sync issues: https://support.f5.com/kb/en-us/solutions/public/13000/900/sol13946.html.
