Thank you both, however, what I need is advice from someone who works with large html pages. My new pages are 1550kb. Would a laptop with 8GB RAM enable the pages to load significantly faster than the 6GB I currently use?
It's everything. I've worked with large pages, but in this case
it's more about Dreamweaver. I won't comment on why so big because it's not the topic and perhaps you don't have a say or option on the content of such pages, so I will approach the tech aspects.
Check your markup, it should be minimal while the rest should be your content, unless your code is clean you might be having trouble due to non optimized markup, but hey you said you are scoring nice on all tests, ok, then
avoid using your FLASH DRIVE, test and measure performance. Hard disk VS flash drives have very diff performance results for different tasks.
Again the markup. I had to use Dreamweaver years ago and some times... I still use it. The thing is there are some markup features that make the browser way slow, this is just about Dreamweaver and there is nothing you can do unless you find another way around, and I mean in favor of Dreamweaver (as your site loads fast according to your comment). Server side includes? yes, you can place server side includes to add up repetitive blocks like navigation etc. In Dreamweaver it will only be a line of text you can't see, but on the server it will be all put together.
It's been years since I moved to pure notepad style editing, no Dreamweaver. It's faster but it demands you manage lines of code and not WYSIWYG. And then moved to my own CMS, this means I rarely see or modify a page on a "web site page" basis, it's just code and the cms (just like any cms you can find) will put the pieces together.
Good luck.
