Is there any free tool for IE so that I can know the page download time and download size?
I'm using IE Web Developer tool but it doesn't show download time/size.
For FireFox, there is an addon called Lori which does it.
Indeed the IE11 dev tools appears to be lacking that nice total time taken. To get around this, in IE11 you can export the data as a CSV. There is an export button next to the start/Stop button on the Network tab.
Convert your ms to seconds and add this figure to the total seconds and you will have your total page load time.
