Hey guys, I am researching for a project and would like to know if I use a 4 core intel cpu with a 10 gig nic card inside how many simultaneous clients should I be able to get if the bitrate per stream is 1mbps (RTMP and HLS)?

I see in the documentation there is a maximum of 10,000 concurrent connections per instance, is this limit even for SD streams?

Thanks for your help.

Minimum recommended production hardware

CPU: Single Quad Core, 3.00 GHz or better

RAM: 4GB

Disk: 2 or more in RAID 0 (striping)

Network: 1Gb Ethernet

With a 1g nic (20% overhead accounted for.) = 800mbs throughput, which is 800 1 mbs streams, or 1600 500kbs streams.

You can use this formula for calculating:

number of users \* stream bitrate + 20% IP overhead = total server bandwidth

You will have to test your actual server/network using the [load test tool](https://www.wowza.com/docs/how-to-get-flash-rtmp-load-test-tool), or monitoring utilization in production. [You must be properly tuned](https://www.wowza.com/docs/general-tuning). And to achieve maximum levels you may have to tune your server and network in other ways outside Wowza.

**NOTE: Java can saturate up to a 5 gig nic.**

Thank you for the detailed reply! I have looked at the tuning docs.
