Hi For a “live” stream with a bitrate of 500 kbps I estimate an absolute maximum of 8000 concurrent users based on the network but if you’re bonding GigE’s together maybe 7000. For “on demand” streaming which I assume will be the main use of this server, it’s hard to say as you would need to speed test the array with load. You can get the Wowza load test tool which supports on demand load testing from here, [https://www.wowza.com/docs/how-to-get-flash-rtmp-load-test-tool](https://www.wowza.com/docs/how-to-get-flash-rtmp-load-test-tool) The server will also need to be tuned and a tuning guide can be found here, [https://www.wowza.com/docs/how-to-do-performance-tuning](https://www.wowza.com/docs/how-to-do-performance-tuning) Jason ---

It’s probably much more than the load test tool can produce. You might have to use 3 or 4 load test clients Richard ---

Correction, I meant it is more than the client (server you are running the load test client on) and/or network can handle. It is possible that it is the limit of the test server’s network bandwidth. Richard ---

It looks like you have tuned for 12 cores. Do you have 12 core machine? Do you have enough available memory to allocate 8000M java heap size? Show the most recent startup lines from your access log, from the last time you re-started Wowza. Richard ---

This line shows there is very little available memory when you started Wowza: > Hardware Physical Memory: 764MB/15927MB > > The number on the left is available memory, on the right it is total memory. So there might be a lot of other activity on this server, other services. > > Richard ---

Also, since Wowza/Java reserves memory (java heap size setting) you are not getting an accurate picture this way. Use JConsole instead: [https://www.wowza.com/docs/quick-start-guides](https://www.wowza.com/docs/quick-start-guides) Richard ---

Hi, According to the startup log as Richard said Wowza thinks that you only have 764MB free. You should be looking at trying to make the amount of memory that you have available accessible by Wowza. I know that you have tuned the server to take 8000MB memory but Wowza can’t see that its free for some reason and this need to be sorted first. Jason ---

Hi Looking closer at you VHost.xml your NetConnections / ProcessorCount is: ```auto 16 ``` To keep to the calculated core count it should be: ```auto 24 ``` Jason ---
