How to Fix Emby Buffering and High CPU Usage (2026)

Buffering and CPU spikes are the most common Emby issues.

This guide explains how to fix them.

1. Enable Hardware Acceleration

Dashboard → Transcoding → Enable GPU acceleration.

Without hardware acceleration, CPU usage will spike during transcoding.

2. Reduce Transcoding

Encourage Direct Play:

• Use compatible codecs
• Avoid unnecessary bitrate conversions
• Match client playback settings

3. Move Metadata to SSD

Metadata stored on slow drives causes:

• Slow browsing
• UI lag
• Background scan delays

4. Monitor Active Streams

Many admins don’t realize how many streams are active simultaneously.

CPU overload often happens silently.
