There is no way to increase performance of Gnash at this time, however, I
still believe using Adobe Flash is still not acceptable.
This is one of those situations where, if you really care moreso about
performance over software freedom, you'd be better off using a different
operating system that doesn't focus on freedom. And yes, it basically sounds
to me like you care for performance over freedom by saying that using Adobe
Flash is acceptable for use in a free software operating system, when, in no
way, it is. It's like saying that you'd like to use proprietary drivers
because they might offer better performance over free software ones, which,
for all I know, could be the case.
There are alternatives, still:
- YouTube has the HTML5 player and an application called minitube.
- For your online school, send them off a letter (electronically or by post)
stating that you can't access their website due to you not agreeing to the
Flash EULA, and ask for alternative ways to access their website. From what
it sounds like you said, you were able to access their website even though it
ran somewhat slow. That's better than what I had to deal with when I was
taking online classes, where it wouldn't even work at all, and I still didn't
install Flash.
I'm getting tired of people talking about how they've installed proprietary
software on a free software operating system, then publically talk about it
in that free software operating system's forum as if it isn't a big deal.
We're here to promote software freedom, not hear how people installed
proprietary software. If you're going to do it, fine, it's your computer.
But, don't talk about it here.
