Biggest downside of Splashtop to me: Only one viewer at a time. % cpu usage by the host app when connected.

And that number goes up if the host's computer runs an Atom processor. I simply don't understand how TeamViewer has optimized their screen transfer so well. Again, small-size images might be highly compressed, but take at least tens of milliseconds to compress. Large-size images take no time to compress, but take a long time to get through. Somehow, TeamViewer completes this entire process to get roughly frames per second.
I've used a network monitor, and TeamViewer is still lagless at speeds of Kbps and 1 Mbps VNC software lag for a few seconds at that transfer rate. During my tree Command Prompt test, TeamViewer was receiving inbound data at a rate of 1 Mbps and still running fps. VNC and remote desktop don't do that. So, how? The most fundamental thing here probably is that you don't want to transmit static images but only changes to the images, which essentially is analogous to video stream.
My best guess is some very efficient and heavily specialized and optimized motion compensation algorithm, because most of the actual change in generic desktop usage is linear movement of elements scrolling text, moving windows, etc. You'll find that TeamViewer rarely needs to relay traffic through their own servers. They do use their own servers to middle-man in order to do the handshake and connection set-up, but most of the time the relationship between client and server will be P2P best case, when the hand-shake is successful.
It sounds indeed like video streaming more than image streaming, as someone suggested. Imagine having a recording codec on your system that can realtime record an incoming video stream your screen. A bit like Fraps perhaps. Then imagine a video playback codec on the other side the remote client. As HD recorders can do it record live and even playback live from the same HD , so should you, in the end.
The HD surely can't deliver images quicker than you can read your display, so that isn't the bottleneck. The bottleneck are the video codecs. You'll find the encoder much more of a problem than the decoder, as all decoders are mostly free. I'm not saying it's simple; I myself have used DirectShow to encode a video file, and it's not realtime by far.
But given the right codec I'm convinced it can work. My random guess is: TV uses x codec which has a commercial license otherwise TeamViewer would have to release their source code. At some point more than 5 years ago , I recall main developer of x wrote an article about improvements he made for low delay encoding if you delay by a few frames encoders can compress better , plus he mentioned some other improvements that were relevant for TeamViewer-like use.
In that post he mentioned playing quake over video stream with no noticeable issues. Back then I was kind of sure who was the sponsor of these improvements, as TeamViewer was pretty much the only option at that time. At the same time it's extremely well optimized. Most likely due to extremely good implementation of x you get much better results with TV at lower CPU load. AnyDesk and Chrome Remote Desk use libvpx, which isn't as good as x optimization and video quality wise.
To me it's the best, however it works between windows PCs or from Mac to Windows only. TV works even from mobiles. Update: article was written in January , so that work was done roughly 10 years ago. Also, I made a mistake: he played call of duty, not quake. When you posted your question, if my guess is correct, TeamViewer had been using that work for 3 years. Read that blog post from web archive: x the best low-latency video streaming platform in the world.
When I read the article back in , I was sure that the "startup—which has requested not to be named" that the author mentions was TeamViewer. Why are you not using VNC? There are plethora of open source solutions, and Tight is probably on top of it's game right now. Also, IIRC the rest of the payload is also squashed using zlib. On top of that Tight is open-source.
If win boxen are your primary target RDP may be a better option, and has an opensource implementation rdesktop. If compressing JPEG is a performance issue for your algo, I'm pretty sure that image comparison would still take away some performance. I'd bet they use best-case compression for every specific situation ie lossy for large frames, some quick and dirty internall losless for smaller ones, compare bits of images and send only diffs of sort and bunch of other optimisation tricks.
And you will need memory to keep previous image states for internal comparison atop of what DF mirage gives you. Introducing Filters for Stack Overflow - the best way to beautify the site where you spend 10 hours a day.

The Question My question is, how is TeamViewer so fast?
I'm hoping there's a TeamViewer developer somewhere here on StackOverflow. Potential Answers Will update this once people reply. My thoughts are, first of all, that TeamViewer has very fine network control.
For example, they split large packets to just under the MTU size and never waste a trip. They probably have all sorts of fancy hooks to detect screen changes along with extremely fast XOR image comparisons. Improve this question.

Expecting an answer on this question hinges on the willingness of a company to share their trade secret. Their primary one at that, the one that keeps them in business. You've got a strong no, the only way to get a yes is to call them.
Ask about their patents, I guess. That's odd. I don't find it's faster than remote desktop myself - far from it! Are you actually testing over the Internet or on some kind of local setup? Have you opened your firewall to permit direct teamviewer connections? Seems like you are only testing on local network.
From my experience it seems like TeamViewer uses lossy compression over slow connection the quality is sometimes really nad. Then depending on your environment processor power on both machines and quality of the network link sometimes VNC might be faster, sometimes TeamViewer. No, I'm not only testing on local networks.

I tried Splashtop, Wow was i amazed. It was smooth and i was able to play video files on the remote system smoothly. It was better than Teamviewer. So for work that requires with detailed images like photoshop or creating textures for 3d assets than TGX is preferred. Just putting my personal experience in here.. It's going back whence it came.. Even initial tests in the office over the LAN yielded mediocre results.
