Hello, your server is a Hetzner Falkenstein 16C 32GB, and the network bandwidth is 1 Gbps.
I checked the server status: the current load average is only 1.6 (on a 16-core machine, CPU usage is about 10%), and there is plenty of headroom for both CPU and memory. If you are experiencing lag during high traffic, the bottleneck is more likely to be the network bandwidth (1 Gbps) rather than the CPU or memory.
I recommend monitoring the network traffic chart on the Dashboard metrics page during peak hours to see if it is approaching the 1 Gbps limit.
Currently, Zeabur does not offer 10G bandwidth server plans. If you confirm that bandwidth is the bottleneck, you might consider distributing the traffic across multiple servers to resolve it.
