Istio-proxy memory consumption high (35mb) even for new cluster with only demo booking app


We provisioned new k8s using rancher on single bare metal server with Istio (1.8) and monitoring ( Prometheus and Grafana) apps.

Deployed Istio booking app on k8s in new namespace called “Istio-demo” with Istio injection enabled.


Istio-proxy is consuming 35-40mb even for just 4-5 services which are part of booking app.

Telemetry is also disabled.

We want to use Istio for mtls for now and not using any advanced features which Istio provides.

Is it possible to disable some features which can reduce memory consumption?
