Been googling for that, and didn't come across a clear definition. TIA! Hey Steve,

Could you explain what “connecting” and “queueing” time measurements as indicated on Firebug’s net panel mean? Been googling for that, and didn’t come across a clear definition.

TIA!

Unlike other packet sniffers, Net panel shows the onload line. So, you can detect what is lazy loaded by seeing if they're after the onload line. @Dave: All packet sniffers that I’ve used show everything that gets downloaded, regardless of when that happens.

I am trying to figure out if the new Net panel accounts for lazy loading (it wont count images that are not yet loaded) I'd really like to test/measure performance of lazyloading vs not lazyloading. Sorry..

I don't know what Start Render corresponds to. @Dave: I don't understand the question. @David: I recommend checking the 3.6 release notes and Honza’s original blog post.

Even when using this new Firebug and Firefox 3.6, I still see the images load in the Net panel. My script starts on Dom Ready.. I have it take all images in a certain container and change the src to /images/1x1.gif and create a new attribute called origin. Origin keeps the correct src on file. When someone clicks to the next section, it loads the images and slides the section into place.. You can check it out here if you wish: http://www.howcast.com/categories so is there something I am missing? BTW: in Firebug's HTML view, the images wont show up.

The fix included help from the Firefox team to add the actual time to each network event." Is there any further information available about the changes in FF 3.6 that helped Firebug more accurately measure network results? Perhaps a bug reference or an entry in the release notes somewhere? “which requires Firefox 3.6 beta). The fix included help from the Firefox team to add the actual time to each network event.”
