Page Size & Loading Time

Image optimisation, overall page size & loading time

[hello2paul]

Hello :)

At present I see my HTML file size & image file which, when added together gives me my total page size. I have also been checking my page loading time using NetMechanic. And, following advice, I shall be trying to keep a page to a max total page size of 50K - giving an approx download time of 10 seconds on a 28.8K modem. Is this the easiest/best way to check overall pages size & loading time?

And finally, having created pages in DWMX2004, optmised the images to reduce the overall page sizes using methods mentioned above, is there a list/explanations of what coding makes a page bigger - i.e. what can be edited out/changed to make the page smaller. Is there a priority listing of what types of coding - Java, HTML, CSS makes a page bigger than another?

Lots of questions, I know. But I'm on a bit of a learning mania at the moment - and today's mania is "Image Optimisation/Page Size" :)

Thanks for you help and expertise.

And so that I may continue this thread let me pose another question....at the page analysis website here:http://www.websiteoptimization.com/services/analyze/ it says how clever I am etc when things are okay. But, when the page size is under 50K, and there is only one image on the page which it deems to be an issue, it will say one of two things:

IMAGES_SIZE - Warning! The total size of your images is 45219 bytes, which is over 30K. Consider optimizing your images for size, combining them, and replacing graphic rollovers with CSS.

IMAGES_SIZE - Caution. The total size of all your images is 24354 bytes, which exceeds 15K. Consider optimizing and creatively cropping your images, and combining them where appropriate. Even better, replace graphic text and form controls with styled text to eliminate unnecessary HTTP requests. Ideally each image should be less than 1160 bytes, to easily fit into one TCP-IP packet.

So, what I would like to know is - with only one image on the page, the total page size being less than 50K, what is the optimum that the one image should be scaled to - 30K or 15K?

50k loading in 10 seconds? I think you will find that in the real world, on a 56K dialup connection, one can expect 1K to transfer in 1 second - that's 50 seconds for a 50K page.

Keep files less than 15K (if you can)

I agree with Matt Probert.
