Hi all, I have a question regarding hardware requirements of a virtual machine. Last week we had a livestream with 150 concurrent viewers at 1.6Mbit/sec. The server is on a 1GB line so bandwidth was not an issue. when we reach the 130 concurrent viewers the video was pauzed every 5 seconds. While the audio was still going al long. Sometimes the complete stream stopped for a couple of seconds… We are running Wowza on Ubuntu 14 in VirtualBox 2 CPU 4GB memory Network: 1Gb Ethernet (shared) Should this be enough to handle 150 concurrent viewers? And what kind of hardware is needed to server 800 mbit’s of data? Thanks in advance Jules ---

Hi Bandwidth is normally the factoring issue for maximum connections, the minimum spec for Wowza is this: System Requirements 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 Java Runtime Environment (JRE) 6 or greater or Java Development Kit (JDK) 6 or greater 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/how-to-do-performance-tuning). And to achieve maximum levels you may have to tune your server and network in other ways outside Wowza.

I talked to the datacenter and they told me there was plenty of bandwidth left. I guess it has something to do with the hardware then. I will try to tune the machine and use the load test tool. Thanks in advance. ---

Hi…as per my knowledge depending on used database engine, type of received values, disk space for keeping a single value may vary from 40 bytes to hundreds of bytes. Normally it is around 50 bytes per value. [pcb assembly process](https://www.7pcb.com/PCB-Assembly-Process.php)
