# Throughput Benchmark

Before testing, the test IPs (85.131.136.82/32, 85.131.136.98/32) have to be [whitelisted](/product-guides/secure-cdn/interface/ip-whitelist.md) in the WebGUI.

{% hint style="danger" %}
Doing Benchmark tests from a single source/provider/region will create artificial behavior due to all requests being routed over the same CDN node.
{% endhint %}

To avoid distorting the results try either of these options:

* a) always test from multiple distributed sources
* b) don't do DNS based testing
* c) test multiple distributed nodes at once

The CDN nodes available for performance testing are (whitelisted IPs):

* 85.131.136.82/32
* 85.131.136.98/32
