Dear Support Team,

I am benchmarking Wowza Streaming Server on Ubuntu 20.04.02 TLS, Intel Xeon E-2288G 8/16 CPU, 32 GB RAM remote workstation. I was expecting to get twise as better results as described in [Wowza\_Transcoder\_Benchmarks\_Transrate1080p.pdf](https://www.wowza.com/resources/Wowza_Transcoder_Benchmarks_Transrate1080p.pdf), but I have two times worse results. I am transcoding, transrating 1080p Bunny to 720p, 360p, 240p, 160p. Transrate results 1 stream - 20% CPU, 2 - 46% CPU, 3 - 60% CPU, 4 - 85% (unusable). Transcoding results 1 - 7%, 2 - 21%, 3 - 45%, 4 - 55%, 5 - 85% (unsuable).  
How would you suggest to proceed with this issue, because I have up to 4 times worse results compared to CPU (8 core, 16 thread) that is in use.  
Transcode, transrate templates are used default, just enabled presets. Wowza Streaming Engine 4.8.11+5 configuration by default is optimized as described in your documentation.

Best regards,  
Rimas

Which server in that PDF are you comparing against (more specifically: which column on page 2)?

Hello Karel,

I benchmarked only software based transrate and transcode functionality. I was not able to succesfully configure Intel QuickSync for Ubuntu 20.04.02 LTS, but it will be next topic.  
We have Server 1 and Server 3 on page 1 in the PDF without hardware acceleration, so it will be Server 1 Default and Server 3 Default columns on page 2. Server 1 Default reaches 68% CPU utilization at 5 inputs, Server 3 Default - 7 inputs at 68% as well. It really well correlates to [PassMark](https://www.cpubenchmark.net/high_end_cpus.html) results: Server 1 - Intel Xeon CPU E3-1285 V3: [6919](https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E3-1285+v3+%40+3.60GHz&id=2894) and Server 3 - Intel i7 6700k: [8968](https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-6700K+%40+4.00GHz&id=2565).  
It is around 1300-1400 PassMark points for every input to transrate. These numbers I used to calculate my system transrate input count. My system has Intel Xeon E-2288G with PassMark score: [17378](https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E-2288G+%40+3.70GHz&id=3546). I would expect at least 12 inputs under 70% CPU load. My result is only 3 inputs under 60% CPU load.  
Karen, how would you suggest to proceed with Wowza Streaming Server as I need all 12 inputs under 70% CPU utilization 🙂. It can be more, but not less.

Regards,  
Rimas

Riman, I’d add a GPU card to that server; a decent NVidia Tesla should be able to handle 15+ channels. In your CPU tests did you use the legacy Mainconcept en-/decoder or did you use the new Beamr? I haven’t done any benchmarking for Beamr and it may have a different impact on CPU because it’s a different coder brand.

Hello Karel,

lets not start straight to the Nvidia Tesla cards and your answer does not relate to what I asked. Wowza provided [benchmarks](https://www.wowza.com/docs/wowza-transcoder-performance-benchmark) for systems with 4 cores, 8 threads CPU’s that in software can handle up to 7 inputs with PassMark score up to 9000. We have 8 core, 16 thread CPU with PassMark score 17000 and can handle only 3 inputs. Isn’t that ironic?  
How many inputs Wowza Streaming Engine can handle with 8/16 cores in your tests? Could you provide what CPUs you used for benchmarks? Could you provide configuration XML files, that you used to get more than 3 inputs?  
I will use these files and hope to provide positive feedback and topic will be closed.

Regards,  
Rimas

I didn’t go straight to the Tesla cards; I just said that as a recommendation. The rest of my message went unanswered.

If you want benchmarks that are comparable to Wowza’s own publications, then you can do your own (see [this article](https://www.wowza.com/docs/how-to-capture-wowza-transcoder-benchmark-statistics)) or your can post a message in the [Hire A Consultant](http://community.wowza.com/c/hire-a-consultant/7) forums and ask someone to do it for you.

Hello Karel,

thank you for the link to [Capture Transcoder benchmark statistics in Wowza Streaming Engine](https://www.wowza.com/docs/how-to-capture-wowza-transcoder-benchmark-statistics) configuration page. I already checked it. Default templates are used for transcoding and transrating , so Mainconcept coder is used by default. I hope we do want to compare apples to apples.  
Karel, do you acknowledge that if we would use Intel Xeon CPU E3-1285, Wowza Streaming Engine 4.8.11+5 on Ubuntu 20.04.02 LTS we should process 5 inputs?  
If we would use Intel i7 6700k Wowza Streaming Engine 4.8.11+5 on Ubuntu 20.04.02 LTS we should process 7 inputs as it is [provided here](https://www.wowza.com/resources/Wowza_Transcoder_Benchmarks_Transrate1080p.pdf). And if we would use much faster processor such as Intel® Xeon® E-2288G with Wowza Streaming Engine 4.8.11+5 on Ubuntu 20.04.02 LTS we should process more than 5 inputs?  
Beamr coder from my experience reduces CPU utilization up to 10-15 % on full CPU load, but it was not mentioned in benchmarks that are provided.

Bay the way, my name is Rimas, not Riman.

Rimas
