Classical tools tell you if servers survive… UbikLoadPack tells you if viewers stay.
The business challenge
Video streaming performance directly impacts :
- Viewer engagement and retention
- Live event success
- Advertising revenue
- Brand perception
In streaming, a few seconds of delay, buffering, or ad insertion failure are enough to lose users and revenue.
Yet most performance testing tools were designed for web applications, not for modern video streaming architectures.
Why generic load testing is not enough
Traditional load testing tools generate HTTP traffic and infrastructure metrics, but they do not reflect how video streaming actually behaves.
They usually :
- Ignore streaming-specific request patterns
- Do not respect realistic segment timing
- Cannot detect playback lag or buffer starvation
- Do not validate ad insertion workflows (SSAI / SGAI)
As a result, teams get technical metrics, but no visibility on user experience risks.
UbikLoadPack Streaming : realistic network-level video simulation
UbikLoadPack Streaming is a specialized streaming performance testing solution, built on top of Apache JMeter.
It operates at network level, but behaves like a real video player.
It automatically :
- Downloads all streaming resources :
. Manifests
. Init segments
. Video, audio, subtitles chunks
. Timed metadata (CMAF, ID3, CData) - Sends requests with realistic timing and pacing
- Simulates player behavior using an integrated PlayerSimulator
- Validates client-side and server-side ad insertion (SGAI / SSAI)
From network data to viewer experience KPIs
UbikLoadPack does not just measure infrastructure load.
It translates network behavior into streaming QoE indicators, such as :
- Startup time
- Buffer level and buffer fill
- Playback lag (late segment arrival causing pauses)
- Rebuffering events
- Segment download latency
- Ad insertion continuity and timing
These KPIs allow teams to anticipate real playback issues before users experience them.
You cannot test video streaming like a web application !
Summary of how Load Test with UbikLoadPack streaming plugin compares to classical load testing:
| Classical Load Testing | UbikLoadPack Streaming | |
|---|---|---|
| Traffic generation | HTTP requests | Realistic streaming traffic |
| Segment timing |  Not realistic |  Real player pacing |
| Buffer behavior | Invisible | Buffer fill & starvation |
| Playback lag detection | No | Yes |
| Low Latency streaming | Not supported | LL – HLS & LL – DASH |
| Ad insertion validation | No | SSAI & SGAI |
| Metrics you get | Servers & bandwidth | Viewer experience KPIs |
| Business risk visibility | Partial | High confidence |
Business value
- Reduce production risks before launches and live events
- Detect buffering and latency issues early
- Protect ad revenues by validating SSAI / SGAI
- Make informed decisions based on realistic viewer experience indicators
- Avoid costly post-production incidents
