+### Performance
+
+Console logging is synchronous and this can cause bottlenecks in some deployment scenarios. For high-volume console logging, consider using [_Serilog.Sinks.Async_](https://github.com/serilog/serilog-sinks-async) to move console writes to a background thread:
+
+```csharp
+// dotnet add package serilog.sinks.async
+
+Log.Logger = new LoggerConfiguration()
+ .WriteTo.Async(wt => wt.Console())
+ .CreateLogger();
+```
