Hi everyone! I would like to ask if there is a bandwidth requirement in TeamViewer?

Hi @nel_07

As discussed in your ticket with us:

The number of hits on your proxy and the slowness are not related.

TeamViewer maintains a "heartbeat" with our servers at all times. This is why your device shows as "online" in TeamViewer systems and also how the software checks for incoming connections. This means every device with TeamViewer will be pinging our router network at all times.

This does not use up much bandwidth at all, in fact the amount is almost negligible.

TeamViewer does not "Open Files" during a remote session.

When using TeamViewer, you are seeing an image relayed to you from the remote device. Then, input from your side is relayed to the remote device. TeamViewer itself is not opening the files, it is simply transmitting an image of you opening the files.

We do have file transfer functionality, but as you are talking about the screen freezing I do not believe this is what you meant.

TeamViewer staff unfortunately cannot fix slowness issues with your network.

Your proxy is a part of your network infrastructure, if this is slowing down connections then you need to either speed up the proxy or bypass it to resolve these issues. If the connections are still slow even without the proxy, then it is doubtful the proxy is the issue.

In your ticket to us, you advised that when you tested this on another network without the proxy, your connection went smoothly. This shows that the problem is somewhere within your network.

In Regards to Bandwidth:

We do not state specific bandwidth requirements as bandwidth is actually a measure of volume over time, not a true measure of "Speed".

Bandwidth requirements make sense for applications like video and file streaming.

On the other hand, remote control applications like TeamViewer are more similar to gaming in an online First Person Shooter

Speed vs Stability

For many users, the issue is not actually speed but stability.

A Youtube video can buffer, meaning that even if your connection cuts out for a few seconds, you will never notice.

TeamViewer however is showing you live information, so you will see these drops in the same way a gamer would.

Bandwidth

It is important to note that traditional "Speed tests" measure bandwidth - this means how MUCH data can be transferred at one time.

This is useful for things like videos and files that need lots of data, but not very useful for things like games or TeamViewer that need fast response times.

Remote Control connections do not need a lot of data, but they do need fast response times - measured in "ping"

It is also important to note that traditional speed tests only measure the speed from one PC to a local server, not between the 2 devices.

Ping

The biggest factor in connections with TeamViewer is the response time between the 2 devices.

If the network connection is sufficient, then the software will still run smoothly, however if there is delays then this can cause some slowness.

For most people,

• more than 100ms of delays noticable.
• 300ms is annoying.
• Above this and the connection will begin to become cumbersome to use.

Checking your connection

We have a speed test built into the software that will show you the speed between the 2 devices.

It is important to look at this when it is slow, not just when it is working as the speed of your connection may change.

Optimising Speed

TeamViewer has the capacity to use very little bandwidth as we optimize our connections to use as little data as possible.

For example by only sending changes in the image rather than whole screen refreshes.

This means that if you are working on a document this would use very little data, but if you have a video running the amount of data and bandwidth requirements will drastically increase.

There are a few more things you can do to reduce delays:

• You can minimise animations on the screen.
• Or, in the software you can select "Optimize speed" to reduce the colour range we use.
• You can also select a smaller resolution while you are connected.

You can also apply more granular quality and speed settings using the advanced configurator.

Turning down either of the bars and turning off "Fast Video Streaming" will decrease data transfer.
