# Optimum System Load

While Unify is powerful, there is a limit to the number of concurrent tasks the onboard CPU can perform efficiently.

The number of concurrent tasks depends on many factors, such as:

- the number of video sources

- what frame rate and bitrate is used for a channel

**Other limiting factors**

- how many channels you have

- how many layouts you have per channel

- how often you switch layouts

- if the system is resizing (scaling) video sources

For best results, we recommend keeping System load usage under 70%.

**Recommendations**

If the system load is higher than recommended, you can:

- Remove unused channels or layouts.

- Reduce the number of channels created.

- Stop channel(s) that are streaming or recording.

- Ensure video sources come in at the right resolution so that Unify doesn't have to up scale or down scale the video source.
