Just open OBS application my internet speed reduced ten times

[Yotsiri Mitpaibul]

I've been streaming on Youtube using OBS as feeder for over two years now. At the beginning like the first years there was no problems. Lately, I found the message saying youtube is not receiving enough data to maintain a smooth streaming a lot. Sometimes, the streaming even stopped.
I try everything, including reduce the output to 640x360 and reduce bit rate to 950 kbps.
By the way my internet speed is 1GB/1GB, which is maximum of the current provider I use.

Lately, I've been discussing with the internet provider a couple of times, as I found that during my live streaming my internet speed drops ten times. I was suspicious of them doing something, but I've talked to all of their technicians who monitored a couple of times during my live streaming and reported no issue during which time.

I then try testing my internet speed. The report saying my upload and download speed is over 900 Mbps both upload and download. But once I open OBS studio application the speed reduced to 242 Mbps uploading and 205 Mbps downloading.

Sometimes I tested live streaming the internet speed reduced to only 16.34 Mbps downloading and 42.5 Mbps uploading. I think that is causing youtube to report not receiving enough data to maintain smooth streaming.

I wonder this is because of my setting of OBS or something else.

Please help.

note the pinned post in this forum regarding asking for help (ie OBS Studio log from streaming session)

understand what a speed test does, how it measures, etc. yes, if using bandwidth (ie streaming) and run a test, that bandwidth isn't available to SpeedTest... presumably you are doing somethign else using upload bandwidth
What are you doing for real-time monitoring of your LAN and WAN connection in terms of bandwidth consumption, protocols, etc?

Do you have 3rd party plugins for OBS Studio (worst offender seems to be streamelements)?

Hi,
Thank you for answering my question.

I tested my bandwidth in two scenarios. As previously described, I run speedtest without OBS and the bandwidth came out close to my subscription, which is nearly 1 Gbps upload and download.

Then, this is the real question,

1. just as I execute OBS my bandwidth reduced to just above 200 Mbps upload and download.
2. I then tested by going live just for the test broadcasting privately, and also run the speedtest, and the upload speed reduced to 16.34 Mbps and upload reduced to 42.54 Mbps.
Understanding that streaming live would eat up my bandwidth, but from 1Gbps down to 42.54 is a lot.
The second question is that just open the OBS application, the bandwidth reduced from near 1Gbps to just over 200 Mbps.

Have I done something wrong in the setting, and should I reset OBS and start every over again.
I have a lot of screen and video clips in the scenes.

Oh, and no I don't have 3rd party plugins for OBS studio.
