I'm working on a web app that allows users to create their own designs, and this app provides the user with a library of images to use in their design. These designs have two images, one low-res image used for the GUI and a high-res one used in the design.
It appears that Chrome/Firefox/IE only load the small thumbnails on page load, and load the larger ones on clicking the thumbnails. On Safari it loads every single image at once which has a huge impact on the page load times. Load time ranges between 5 to 30 seconds on Safari compared to 1 to 2 seconds on other browsers.
Safari debugger:
Total resources: 283
Resource size: 277 MB
Load time: 29.78s
This is Safari 7.0.5 running on OSX 10.9.4 and also impacts Safari 5.1.7 running on Windows 7.

I've built a small game that running perfectly while on local (from Flash). It's a small 60-fps game. Using the same computer, I'm playing the swf using a browser (Chrome, Firefox, Explorer) however it's running extremely slow. I'm using swf monitor (and Browser monitor) there you can see clearly the swf is running with 61/60 fps however this is just not true. Seem like the browser is forcing swf fps down to around the 20 fps or so. I've also tried Wmode (direct / GPU) but nothing. What is going on?
After updating my graphic card drivers, everything works perfectly even on Browser. Flash can handle it perfectly without updated drivers, but on a browser it's a must to have, else it will damage application performance and FPS.
When i load my website on IE10/9/8 some images wont load.
and if i reload the page, the previous images loads perfectly, but some other images wont load.
And if i remove the browser cache, and refresh the page, same thing. some images load and other w'ont load. you can also see that problem in the portfolio page
thanks
Have you tried loading the webpage in alternative browsers? I'm loading it in Google Chrome and all the images load perfectly fine. Internet Explorer utilities your graphics card as well as your processor to load images to make it faster, which might be totally irrelevant for this question but perhaps your graphics card/processor is causing you issues?
If it's working in other browsers, then use them as opposed to Internet Explorer. It will be a bug with their browser and it's compatibility with whatever system you're using. It's the worst browser to use in all honesty.
I have created a Flash game which plays at 60 frames per second. It plays fine in all browsers except Internet Explorer 8 and 9; in these cases, it seems to be half (or less than half) the intended frame rate.
I have tried embedding it even by using Flash Authoring Tool's own html code, as well as the swfobject method, but to no avail. In all cases, GPU acceleration is enabled.
It's also not a matter of CPU performance, since it is tested on the same computer with all other applications closed. The problem only rises with IE.
One final peculiarity to consider : I have loaded FRAPS to count the actual rendering frame rate and it shows it to be 60 fps (inside IE), although it's crystal clear that this is not the actual speed achieved.
sounds like flash isn't properly installed on your IE browser
Try the following (assuming you have Adobe Flash Player v10.2 installed):
• Restart your computer.
• Open Internet Options (located in the Control Panel).
• Click on the Advanced tab.
• Click on the Reset button, place a check next to Delete Personal Settings and then click Reset.
• Launch IE9 and Adobe Flash Player will be properly enabled.
then try your tests again
GPU acceleration is not always the best solution. It depends on the way you have code the app.
Try another wmode value.
i'm developing a website which is using a background video for the home page.
that video has pretty small filesize (about ~300 kb) and the problem is that it is kinda blocking firefox - which means when clicking a link to a different page, it takes about 10 seconds until firefox will start loading it. i've checked the taskmanager, plugincontainer.exe is eating ~26% cpu on my machine.
any ideas how to optimize this?
I googled optimising video backgrounds, and it gave me this page, it talks about streaming videos and how to optimise it, its essentially what will be causing the problem I would assume.

There's a site that uses CSS and JavaScript a lot.
The site loads fine in Firefox, almost instantly. When opening the site in any webkit-based browser (I've tried midori, arora and vimprobable2), CPU load spikes to 100% and stays like that for about 60 seconds. Then the site loads. As soon as I want to scroll the site using the mouse wheel - CPU load jumps to 100% again.
Is it possible to debug the site somehow when having it opened in a webkit-based browser and find the reason of high CPU load? Is there something like Firebug for webkit-based browser that can be used for this?
I'm sure that it doesn't happen due to DNS, because I can reproduce the issue by downloading the html pages locally and load it from there in browsers. It loads fine in Firefox, CPU load jumps to 100% in webkit-based browsers.
You can use Firebug Lite within Safari:
