Boot Analysis

The Boot Analysis page helps you answer “why does my computer take so long to start?” by showing which services and processes contribute the most to your boot time.

What You’ll See

Linux: Nexis runs systemd-analyze to get your total boot time, and systemd-analyze blame to break it down by service. Each service is ranked from slowest to fastest and labeled by severity:

Label	Duration
High	5 seconds or more
Medium	1-5 seconds
Low	Under 1 second

If systemd-analyze isn’t available on your system (for example, on a non-systemd distribution), the page shows “not available” instead of a breakdown.

macOS: Per-service startup timing requires elevated privileges that Nexis doesn’t request, so macOS shows your total uptime since last boot instead of a per-service breakdown.

Refreshing the Analysis

Boot analysis runs in the background so the interface stays responsive while it works. Click Refresh at any time to run a new analysis on demand — useful after you’ve disabled a startup service and want to confirm it’s no longer showing up in the breakdown.

Acting on What You Find

Boot Analysis is a diagnostic view — it doesn’t disable anything directly. If you spot a slow service you don’t need at startup:

• Linux: disable it with your service manager, or use the Services page in Nexis to disable a systemd unit.
• Check the Startup Apps page for user-level applications that launch at login — these are separate from system services and are the more common source of a slow desktop login.

What’s Next

Review and manage applications that launch automatically at login on the Startup Apps page.
