+The {agent} resources consumption is influenced by the number of integration and the environment its been running on.
+
+Using our lab environment as an example, we can observe the following resource consumption:
 
-The following are the minimum system requirements for installing {agent}.
 // lint ignore mem

 === CPU and RSS memory size
 
-// lint ignore 2vcpu 1gb
-Minimum requirements have been determined by running the {agent} on a GCP `e2-micro` instance (2vCPU/1GB).
-The {agent} used the default policy, running the system integration and self-monitoring.
-
+// lint ignore 2 vCPU 8.0 GiB
+We tested using an AWS `m7i.large` instance type with 2 vCPUs, 8.0 GB of memory, and up to 12.5 Gbps of bandwidth. The tests ingested a single log file using both the <<output-elasticsearch-performance-tuning-settings,throughput and scale preset>> with self monitoring enabled.
+These tests are representative of use cases that attempt to ingest data as fast as possible. This does not represent the resource overhead when using {integrations-docs}/endpoint[{elastic-defend}].

 Adding integrations will increase the memory used by the agent and its processes.
