+# Improved polling performance
+
+SC4SNMP now offers beta support for improved polling performance.
+
+While this is in beta, we encourage users to explore it. Although we've conducted extensive testing, occasional issues may arise.
+Your feedback during this phase is crucial in refining and optimizing and can be shared using [issues](https://github.com/splunk/splunk-connect-for-snmp/issues).
+To get started, the zip file with helm chart must be downloaded. It can be found on [feat/improve-polling-time](https://github.com/splunk/splunk-connect-for-snmp/pull/976/checks) branch.
+
+On the left-hand side click `create-charts-zip`:
+![Workflows](../images/improved-polling-tmp/actions-view.png)
+
+<hr style="border:2px solid">
+
+At the bottom of the page in the `Artifacts` section there will be 
+`charts` package. Download it and unzip it in your environment.
+
+![Workflows](../images/improved-polling-tmp/charts-zip-view.png)
+
+In `values.yaml` set the following image settings:
+
+```yaml
+image:
+  repository: ghcr.io/splunk/splunk-connect-for-snmp/improved-polling-time
+  tag: "latest"
+```
+
+Change the directory to `charts/splunk-connect-for-snmp` and run `microk8s helm3 dep update`. You can exit `charts/splunk-connect-for-snmp` directory.
+While running `microk8s helm3 install` or `microk8s helm3 upgrade` commands, path to the helm chart must be modified. 
+In the [sc4snmp installation](./gettingstarted/sc4snmp-installation.md#install-sc4snmp) documentation, the following commands are presented:
+``` bash
+microk8s helm3 install snmp -f values.yaml splunk-connect-for-snmp/splunk-connect-for-snmp --namespace=sc4snmp --create-namespace
+```
+``` bash
+microk8s helm3 upgrade --install snmp -f values.yaml splunk-connect-for-snmp/splunk-connect-for-snmp --namespace=sc4snmp --create-namespace
+```
+
+In order to use this beta release, `splunk-connect-for-snmp/splunk-connect-for-snmp` needs to be changed to the path of the `charts/splunk-connect-for-snmp` directory. 
+
+To learn how the new improved polling works, refer to the documentation [Poller Configuration - Define maxRepetitions](https://github.com/splunk/splunk-connect-for-snmp/blob/feat/improve-polling-time/docs/configuration/poller-configuration.md#define-maxrepetitions) 
+for instructions.
+
+Your involvement in testing new polling support is pivotal, and we look forward to hearing about your experiences.
