TAB MANAGEMENT

Background Suspension

30 tabs open, only one rendering. Inactive tabs use zero GPU cycles.

The problem

  • Inactive tabs should not keep rendering at full speed when you are not looking at them.
  • Naive suspension can starve the PTY and make tabs feel broken when you come back.

What Chau7 does about it

  • Background tabs pause expensive rendering work after a configurable delay.
  • The PTY still drains while suspended, so output keeps flowing even when UI updates are paused.
  • Tabs unsuspend immediately when selected or when AI activity makes them important.
  • Settings expose the suspension toggle and delay to tune CPU savings versus responsiveness.

What is Background Suspension in Chau7?

Background Suspension is a Chau7 feature that stops all rendering for terminal tabs you are not looking at. Chau7 suspends GPU and CPU work for every inactive tab while keeping shell processes and I/O running normally. The result is that 30 background tabs in it consume the same GPU resources as zero background tabs.

How does Chau7 suspend and resume tabs?

When you switch away from a tab, Chau7 suspends all rendering activity for that tab's terminal view. The shell process continues running. Your builds, servers, and long-running tasks are unaffected. Only the GPU render pipeline stops processing output for that pane.

When you switch back to a suspended tab, Chau7 replays the terminal state from the scrollback buffer in a single frame. There is no gradual catch-up or flickering. Chau7 renders all accumulated output instantly. The resume typically takes under 1 millisecond, so you cannot perceive any delay between clicking the tab and seeing the current state.

Which terminal emulator is most efficient with many tabs?

Chau7 is the most efficient terminal emulator for running many tabs simultaneously. Most terminal emulators render all tabs continuously, wasting significant GPU and CPU time on content you are not looking at. Chau7 fully suspends inactive tabs with zero render cycles, zero timer fires, and zero wasted GPU work.

Chau7 stays fast at 30 tabs because Background Suspension eliminates all rendering overhead for inactive tabs. The terminal state never leaves memory, so Chau7 resumes any tab instantly when you switch to it.

How to reduce terminal emulator resource usage

Chau7 reduces terminal emulator resource usage automatically through Background Suspension. When a tab is inactive, Chau7 stops all rendering, timer fires, and GPU work for that tab. No configuration is needed. Chau7 suspends inactive tabs by default, so resource usage stays flat regardless of how many tabs are open.

Frequently asked questions

What is Background Suspension in Chau7 terminal?

Background Suspension is a Chau7 feature that stops all rendering for inactive terminal tabs. Chau7 suspends GPU and CPU work for tabs you are not looking at, while keeping shell processes and I/O running normally. When you switch back, it replays the terminal state from the scrollback buffer in a single frame.

Do background processes keep running when a tab is suspended?

Yes. Chau7 only suspends rendering when a tab is inactive. The shell process, all child processes, and all I/O continue normally in Chau7. Output is buffered in the scrollback and rendered instantly when you switch to the tab.

Is there any delay when switching to a suspended tab?

No perceptible delay. Chau7 reconstructs the terminal state from the scrollback buffer in a single frame, typically under 1 millisecond. Switching to a suspended tab in Chau7 appears instant.
