(In reply to akulle12 from comment #0) > The Youtube player feels very sluggish when having Electrolysis and Media > Source Extensions enabled. Sluggish how? It's just as slow to react for seeks here (If it actually succeds and doesn't hang) And when it hangs it becomes totally unresponsive. What I do notice is that sometimes videos play quite well (both e10s and normal window) for a while but then start to hang all the time on seeks or just by themselves.

I mean that it's slow to react, for example when I click on the video to pause it, it can take seconds before it actually reacts to it.

akulle: do you have any add-ons installed, such as Adblock Plus? We had some YouTube performance bugs related to Adblock Plus (bug 1062713), but they should have been fixed.

MSE does more processing on the main thread than the regular video element. Perhaps this is also the case for e10s.

This blocks e10s not MSE for the purposes of priority at this point.
Priority: -- → P5
I'm going to close this because e10s works swimmingly. Re-open if there are still issues.

I think youtube itself is heavy and that makes the player and practically everything else also sluggish if you have an older PC. E10s just makes it somewhat worse, and you get the spinner shoved in your face all the time.
