Low Latency

Feel-at-home performance with minimal input delay over your local network

Get started

Network input forwarding over your local LAN. Feel-at-home performance with minimal input delay.

Latency is the most important quality metric for a KVM solution. If there is a perceptible delay between what you type and what appears on the remote machine, the experience becomes frustrating and unusable. HelloControlDesk is built from the ground up to minimise input latency by operating entirely over your local area network, where round-trip times are typically under 1 millisecond.

The input forwarding pipeline is kept as lean as possible: mouse events and keystrokes are captured, serialised, encrypted, and transmitted in a tight loop with no unnecessary buffering. On a wired connection the delay stays very low; over Wi-Fi it depends on the quality of your network.

HelloControlDesk never routes traffic through the cloud. Your keyboard and mouse events travel directly from your server to your client machine over the local network, meaning latency depends only on your LAN, not on server round trips or internet conditions. On a good local network, this architecture keeps HelloControlDesk responsive in everyday use.

How it works

  1. 1

    The server application captures keyboard and mouse events on the machine you type on.

  2. 2

    Events are encrypted with TLS and sent straight to the client over your local network, Wi-Fi or Ethernet. No cloud relay is involved.

  3. 3

    The client replays them on its own system. Delay depends on your local network, not on an internet connection.

  4. 4

    The shared clipboard takes the same direct path between machines.

When it is useful

Typing on a second machine for long stretches

Writing code or documents on the machine next to you: input travels over the local network only, so there is no internet round trip between a keystroke and its arrival.

Mac and PC on a wired office network

Both machines connected to the same Ethernet network: the input path stays on your own cabling, from one machine to the other.

Home office over Wi-Fi

A laptop and a desktop on the same Wi-Fi network work together; responsiveness then depends on the quality of that Wi-Fi.

Limits and requirements

  • HelloControlDesk works only between machines on the same local network, over Wi-Fi or Ethernet. It does not work over the internet.
  • Responsiveness depends on your network: a congested or weak Wi-Fi link shows up as delay, a wired connection is usually steadier.
  • No latency figure is guaranteed; what you get reflects your own local network.
  • Server and client run on macOS and Windows.

Frequently asked questions

Why does HelloControlDesk stay responsive?

Keyboard and mouse input travels directly between your machines over the local network, never through the cloud. Latency depends on your Wi-Fi or Ethernet, not on the internet.

Does it work over the internet?

No. HelloControlDesk only works between machines on the same local network. That limit is what keeps the input path short and the delay low.

Is a wired network required?

No. Wi-Fi or Ethernet both work. A wired connection usually gives the most stable results, but the choice is yours.

Does HelloControlDesk guarantee a response time?

No. Input travels on your local network and the delay depends on it. HelloControlDesk does not publish or guarantee a latency figure.

Does the clipboard use the same path?

Yes. Clipboard content travels directly between your machines over the local network, inside the same TLS-encrypted connection as keyboard and mouse input.
