Description

Our RUM/Real User Monitoring capability has the ability to identify Network Grade. This makes it easier for you to know whether the Network is at the root-cause of a slow page.

Configuration

This works for both Germain RUM “Browser Extension” or “JavaScript”.

Modify SLA

The following line can be added to the Germain RUM’s init-script to modify the list of poor grades (i.e. what is considered a "poor network"):

settings.plugins.poorNetworkLocation.poorGrades = ['slow-2g', '2g', '3g'];

For example, ‘3g' can be removed so only '2g’ and below are considered poor.

ECT	Minimum RTT	Maximum downlink	Explanation
`slow-2g`	2000ms	50 Kbps	The network is suited for small transfers only, such as text-only pages.
`2g`	1400ms	70 Kbps	The network is suited for transfers of small images.
`3g`	270ms	700 Kbps	The network is suited for transfers of large assets, such as high resolution images, audio, and SD video.
`4g`	0ms	∞	The network is suited for HD video, real-time video, etc.
