Mac OSX Firefox 4 - 刷新速度非常慢
有没有其他人发现在 Mac OS X 上使用 Firefox 4 时 Flash 非常慢？
当 .swf 变得大于 ~1000px 时，就会发生这种情况，整个 .swf 滚动、响应等都很慢。
有没有其他人注意到这一点并找到了提高速度的方法？
谢谢！
Has anyone else found that flash is VERY slow when using Firefox 4 on Mac OS X?
This happens when the .swf gets larger than ~1000px, the whole .swf is slow to scroll, respond, etc.
Has anyone else noticed this and figured out something to enhance speed?
Thanks!

我一直注意到 Flash 在 Mac 上比任何其他操作系统都慢。我相信这与 Mac 对任何应用程序的锁定有关，但也可能是因为您使用的是 wmode='transparent' 或者应用程序中有很多性能不佳的代码。
I've always noticed Flash to be slower on Macs than any other OS. I believe it has something to do with the lock that Macs have on any application, but it could also be because you're using wmode='transparent' or there's a lot of bad performing code in your application.
这实际上取决于您在 SWF 中所做的事情，但是当 SWF 大于 1000px 时，您的问题就会发生，它可能会绘制大量矢量。如果您有相关 SWF 的链接，那么就更容易找出来。
此外，正如 J_A_X 提到的，Mac 直到最近才允许 Flash Player 访问硬件加速
It really depends on what you're doing in the SWF, but seeing as your problem is happening when the SWF gets bigger than 1000px, it's probably drawing a crap ton of vectors. If you have a link to the SWF in question, it'd be easier to figure out.
Also, as J_A_X mentioned, it's only recently that Macs have allowed Flash Player access to hardware acceleration
遇到了同样的问题，并且仅在 firefox4 OSX 中。我们设法通过删除页面 CSS 来显着提高速度，该 CSS 将背景图像缩放到超出窗口限制 - 我猜测这个过程是由 webkit 交给 GPU 的，但在 Firefox 中则没有那么多。我建议仔细查看 css 中任何超过 100% 的值...
这甚至使页面上嵌入的 YouTube 播放更加流畅。
ran into the same problem and ONLY in firefox4 OSX. We managed to get a significant speed boost by removing the page css which was scaling a background image beyond the window constraints - my guess is this process is handed off to the GPU by webkit but not so much in firefox. i'd suggest looking carefully at any 100%+ values in the css...
This even made youtube embeds on the page play smoother.
