AP122 high CPU usage when streaming.

[sergi_dupe]

Hi,

I have an AP122.

When I stream a 4kUHD movie (Plex server detects that the movie is encoded at 139Mbps) to my TV (the TV is connected at 5GHz band and 1% rx CRC rate according to tech log), the movie has to buffer all the time. Diggin deeper in the issue, it turns out that the AP122 CPU is about 98% when streaming that movie.

This is the log message: 2019-11-19 20:24:36 warn  ah_top: CPU rate overload.

The process that uses the 98% of CPU resources is :

3 root      RW [ksoftirqd/0]

My question is: is AP122 capable of dealing with that with a proper configuration (this is, reduce the ksoftirqd/0 demands) ? or I have reached a hardware limitation ?

Thank you!

Hello ExtremeNetworks Community,

The AP122 experiences high CPU usage (98%) while streaming 4K content at 139 Mbps, likely due to its processing limitations. Upgrading to a more powerful access point or reducing the stream quality could help resolve this issue.

It seems like the AP122's CPU is being overloaded due to the high bitrate (139 Mbps) of the 4K UHD movie. This indicates that the device may have reached its hardware limitation. You can try reducing the stream's bitrate by transcoding the video on the Plex server or lowering the quality settings for streaming. Additionally, ensure your AP122 firmware is updated and check for configuration tweaks, such as limiting other processes or optimizing the wireless network.

For hassle-free streaming and IPTV content, consider to descargar MagisTV, which offers smooth streaming experiences without heavy device demands.
