- Storage throughput bottleneck
- High concurrent stream load
- Client decode limitations
Problem Description
When your UniFi Protect UniFi Timeline Performance isn't working as expected, it usually traces back to one of a small number of causes — this guide covers them in order, starting with the most likely.
Symptoms
- Long delay while scrubbing
- Playback jumps
- UI stalls with high camera counts
Recognize these? Here's what usually causes it.
Common Causes
- Storage throughput bottleneck
- High concurrent stream load
- Client decode limitations
Most fixes happen in the first 3 steps.
Do not diagnose timeline lag from one low-power client only.
Tools & Requirements
Step-by-Step Solution
Measure storage performance
Validate disk throughput and latency under playback load.
Limit concurrent heavy streams
Reduce simultaneous high-resolution playback sessions.
Compare client capability
Test timeline speed across different client devices.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Timeline performance is constrained by both server and client resources.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.

- High concurrent stream load
- Client decode limitations
