|Recording Mode||Test Results|
|Single stream audio and video recording||Concurrent recording of 350 rooms, the recorded video files lag. Suggest 300 concurrent rooms|
|2-channel mixed-stream audio and video recording||Concurrent recording 45 rooms, 75% CPU usage. Suggest 40 rooms concurrently|
|2-channel mixed-stream pure audio recording||Concurrent recording 230 rooms, 85% CPU usage. Suggested concurrent 200 rooms|
The performance bottleneck of single-stream recording is the network bandwidth. If you need more concurrent single-stream recordings, you need more bandwidth and at the same time need to pay attention to the use of disk I/O. The performance bottleneck of mixed stream recording is CPU. If you need more concurrent mixed stream recordings, you need a higher performance CPU.
