Network speed: Definition, causes, tools
Network speed is a commodity for both private users as well as professional organizations. Private users often wish to learn if their providers are actually delivering the DSL that is promised in their contracts. A number of free online tools measure network speed. In professional settings, administrators keep an eye on their network speed, data transmission, and network throughput. They seek to identify the areas that are putting too much strain on their networks, or that threaten to do so in the future.
There can be many different reasons for a network slowing down. Individual applications may turn out to be bandwidth hogs. Backups, too, can lead to problems with data throughput. And sometimes the problem lies in an overloaded switch, or with the routing, a network cable, or an outdated router that is unable to process the increased amount of traffic.
In professional settings, administrators have a choice of three different solutions for network performance monitoring: they can opt for open source software, search for a variety of specialized tools, or choose all-in-one software. PRTG is a centralized tool that identifies, measures, and tests all the important data in your network. PRTG saves time and stress. You can also access bandwidth usage information over longer periods of time, and use the built-in reporting system to create custom reports as HTML, PDF, XML, or CSV files.
Measuring bandwidth and
network speed with PRTG
PRTG comes with several preconfigured SNMP sensors for a variety of different network manufacturers. These sensors can be used regardless of the manufacturer, however, as long as the target device supports SNMP. By using SNMP sensors for traffic monitoring, you can quickly determine the server or application that is responsible for the spike in traffic and the resulting low bandwidth.
More than 250 sensors
You'll find over 250 sensors our sensor list. These sensors are part of a single, centralized tool which allows you to perform comprehensive monitoring and keep a constant eye on your network. Our sensor list is continually being updated.
What is a sensor?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
7 good reasons to go with PRTG
With PRTG, you’ll keep a constant eye on your system and applications. Let one single tool monitor your entire network – and finally enjoy some peace of mind.
When glitches occur, you’ll be notified at once – often with plenty of time to prevent your system from crashing.
PRTG can be used with all the biggest manufacturers and applications. Our network monitoring software is certified by IT industry leaders.
PRTG is administered via an intuitive dashboard. Use the default dashboard or create your own custom version.

Many administrators want...
A new tool
The network slows down, it takes forever to transfer large files, servers and workstations are slower after installing new applications, the website loads at a snail’s pace: in situations like these, many administrators begin to look for a tool to test their network transmission speed. PRTG offers in-depth network monitoring so you can get to the root of the problem faster!
A centralized tool
So many problems, so many tools...Even the best of administrators can lose sight of things and become frustrated with the amount of time that is required to keep their networks afloat. PRTG is a centralized tool for your network, system, and applications. With PRTG, efficiency is guaranteed!
A different kind of tool
Open-source software comes with many limitations and often takes a great deal of time to get up and running. And professional versions of this software usually come with fees. PRTG is different: when purchasing a license, you get the whole package! And thanks to our Network Auto Discovery feature, your monitoring will be set up in no time.

Over 95% of our customers recommend PRTG
Paessler AG worldwide trialled PRTG in over 600 IT departments.
The aim was to tune the network monitoring software closer to the needs of the administrators.
The result of the survey: over 95% of the participants would recommend PRTG - or already had.
How do I test network speed with PRTG?
HTTP Advanced sensors:
- Create three sensors for various files found on different servers.
- Let the sensors run for a few hours in 5-minute intervals.
- The sensor overview provides the bandwidth speed in kbps during the download.
To the HTTP Advanced Sensor
You’ll get a good feel for the possible transmission speed, even if the actual bandwidth is unable to be determined with 100% accuracy. Be sure to practice good judgment when carrying out this procedure to avoid putting unnecessary strain on your data line. You can also follow the suggestions found in our practical tip below.
Take a closer look at the procedure for the random testing of data throughput on our bandwidth monitoring page.
Practical tip: “Hey Mathias, what would you tell administrators who wish to monitor their bandwidth?”
“Instead of trying to measure bandwidth by way of an extra, simulated load, you should have a look around for actions which do that anyway – and then monitor them. For example, when you perform backups, you often put great strain on the bandwidth and can thus easily recognize shortages or bottlenecks.”
Mathias Hengl, PRTG developer at Paessler AG
