Overview
From time to time, there may be a requirement to test the speed throughput of Kerio Control in its environment to ensure that the Kerio Control configuration is not limiting the internet connectivity speed.
This article provides the guidelines for running effective Speed Tests.
Guidelines for Running Effective Speed Tests
-
During the test, ensure that no other intensive bandwidth utilization application is using Kerio Control.
-
Use any of the native apps from Speed Tests. Results from browser JavaScript or browser plugin results are not accepted.
-
Ensure that the PC where you are performing the speed test meets the following criteria:
-
It is connected via wire to Kerio Control.
-
It has adequate resources, especially CPU. Consumption should be low without the speed test.
-
-
Disable Debug logs on Kerio Control.
- Repeat the test a couple of times, changing the test server (select a physically nearby server). Ideally, repeat the test at different times of the day as the results can vary based on external factors.
Elements That Can Affect Kerio Control
-
Number of Rules
-
Debug logging
-
Size of the files being transferred
-
Services that are enabled
-
Type of Internet Connectivity
-
Network Interface type
Note: In the case of PPPoE connection, it is recommended to consult with the ISP to find out the correct MTU value and change it in the Kerio Control settings. -
Custom Bandwidth rules and QoS
Additional Information
Kerio Control is not simply a Firewall but a UTM (Unified Threat Management System). Hence it has additional built-in features like AntiVirus Engine, IPS System, Web Filter, Content Filter, Anti-Spoofing, etc.
As a lot of inspections are done at each of these layers, usually there would be a drop of 25% to 30% in the internet speeds. So it can be assumed as normal behavior if the internet speeds are reduced by 20% to 30% after passing through Kerio Control.
If the speeds deteriorate beyond 50%, then it is abnormal and needs to be investigated and reported to Engineering after initial troubleshooting by Customer Support.
