What is difference between produce.close() and produce.pause()? Is there any difference in CPU’s performance when I use produce.pause() rather that produce.close()? ---

`close()` _closes_ the Producer. Terminates it and hence makes it unusable anymore. You don’t want to use it just to save CPU. > **[mediasoup :: API](https://mediasoup.org/documentation/v3/mediasoup/api/#producer-close)** > > Cutting Edge WebRTC Video Conferencing ---

Thank you. I have 1 producer and 7 consumers and when I see CPU usage for mediasoup-worker, these are the results. When I paused their producer the CPU usage is around 13.2%. When I closed their producer it reached to almost 11.4%. You think it’s normal? ---

Hi, Ali. We write full documentation for something: > **[mediasoup :: API](https://mediasoup.org/documentation/v3/mediasoup-client/api/#ProducerOptions)** > > Cutting Edge WebRTC Video Conferencing ---

Thank you. Yes. You’re right and I’m sorry about that. But I didn’t find anything about how CPU behaviors when producer is paused. I got that when we close producer it becomes no longer usable. ---

Look for `zeroRtpOnPause` option. ---

Thank you. You are right. I didn’t read anything. I’ve done what you said, it worked and I’m so happy now. 😊 ---

Hi dear Iñaki. I tested `zeroRtpOnPause=true` option for 2 weeks and now I realized that in comparison with `producer.close()`, it uses more CPU. I have 7 producers and 200 consumers (every producer has about 30 consumers), my server has 4 CPUs and all of these eat about 70% of all CPUs. Maybe my users don’t use browsers that support `zeroRtpOnPause`. Am I somewhere wrong. ---

Please avoid direct mention. I’m not the only one here that can give support. You can check (via stats or “trace” events) in server side whether those `Producers` in mediasoup are receiving RTP or not while paused. I cannot speculate much more if you don’t confirm that. ---

I’m sorry about that I didn’t know that. Maybe you’re the good one. I’ve checked that and all browsers except chrome do not support `zeroRtpOnPause` option. Because of CPU saving of server and battery lifetime of devices I think `producer.close()` is better choice rather than `zeroRtpOnPause`. I said that because I control students with teacher and I do that with sending some commands to students for behave as a producer or not. I’m going to test it in this week and report it (I did it before but I didn’t pay attention what the result was). Thank you for being nice.
