 ## Send data to Pyroscope OSS or Grafana Cloud Profiles
 
+To configure the Golang SDK to send data to Pyroscope, replace the `<URL>` placeholder with the appropriate server URL.
+This could be the Grafana Cloud URL or your own custom Pyroscope server URL.
+
+If you need to send data to Grafana Cloud, you'll have to configure HTTP Basic authentication.
+Replace `<User>` with your Grafana Cloud stack user and `<Password>` with your Grafana Cloud API key.
+
+If your Pyroscope server has multi-tenancy enabled, you'll need to configure a tenant ID.
+Replace `<TenantID>` with your Pyroscope tenant ID.

+### Option for handling increased memory usage
+
+Pyroscope may require additional when tracking a lot of objects. For example, a Go service that indexes large amounts of data requires more memory.
+This tracking can lead to higher CPU usage and potential CPU throttling.
+
+You can use `DisableGCRuns` in your Go configuration to disable automatic runtimes.
+If this flag is enabled, there is less GC running and therefore less CPU resources spent.
+However, the heap profile may be less precies.
 
-If you need to send data to Grafana Cloud, you'll have to configure HTTP Basic authentication. Replace `<User>` with your Grafana Cloud stack user and `<Password>` with your Grafana Cloud API key.
+Add `DisableGCRuns: true` to the pyroscope.Start(pyroscope.Config) block.
 
-If your Pyroscope server has multi-tenancy enabled, you'll need to configure a tenant ID. Replace `<TenantID>` with your Pyroscope tenant ID.
+```go
+pyroscope.Start(pyroscope.Config{
+  ApplicationName:   "example.golang.app",
+  ServerAddress:     "<URL>",
+  // Disable automatic runtime.GC runs between getting the heap profiles.
