Status: UNCONFIRMED

(Core :: DOM: Events, enhancement)

Description

[Wellington Torrejais da Silva]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:72.0) Gecko/20100101 Firefox/72.0

Steps to reproduce:

• Developer
• Many tabs, searching many things
• Audios pauses and breaks frequently
• I see apparent slowdown on Spotify Web Player "FETCH" requests

Suggestions:

• Please prioritize fetch request and other media requests over others networks requests.
• Prioritize Spotify and media player tabs than others tabs.

Request headers:

GET /audio/0b09d174326fd16289707ef4349e9a839d7dda28?1574212001_k7G2S2l5rWvKukvQ9qh9-aA15tRgyEtwSuzBPTI2Ef0= HTTP/1.1

Actual results:

Slow fetch requests responses.

Expected results:

Improve Spotify audio play priority over other non multimedia tabs.

Thanks!

I cannot properly reproduce this issue on my systems. Setting component as (Core) DOM: Events.
NI me if further testing is needed.

@reporter: Did you reproduce this issue in Nightly v72.0a1 on a Linux OS?

Hi Bode,

Yes, I can. Try to test in slow machine or PC with limited computational resources. 




Thanks!

Hi,

I think the order off resources load is more visible in slow PCs.
But I'm still suggest the optimization for all scenarios.

Thanks!

I have reattempted to confirm your issue on Ubuntu 18 by forcing CPU to 100% and memory to almost 100% on a pretty slow machine, but the Spotify sang nicely.
We should leave this enhancement to be investigated by a developer. Thank you.

Maybe I'm just imaging things, but "pulling" spotify tab to a separate window (thus making its performance not depend on my thousand-tabs strip usual overhead) seemed to do the trick for me.

This may also cause bug 1586518.
