download time of webpage

Looking for a tool that measures the downloadtime of a webpage

Hi,
does anybody know a tool that measures the downloadtime of every single element in a webpage.
I have a webpage with content (graphics) that are hosted on different servers and would like to check how much time it takes to load each one of them, important is that I can put download speeds in a relation to each other, ie graphics from server A take that much time graphics from Server B,
thanx in advance

This is really difficult to work out: different servers will give different response times depending on the time of day and how busy they are, the network is, your ISP is, etc. Also, download times will vary according to where the visitor is, and of course how they connect to the Internet.

Generally you should try to make your pages load as fast as possible (as you proabably know ;)). I tend to look at overall page weight, as well as in-browser rendering. Homesite will tell you the page weight and indicative download times, and if you avoid whole-page tables your design will render progressively (i.e. a bit at a time). Specifying width and height also helps the page render without waiting for images to download.

If you have one server noticeably faster than another put everything on it and close the slow one! HTH.

Thanx for your input. I am working for a Net-audit company we are offering audited weblogs for sites running advertisments. Every customer inserts a small script on each page he wants to measure which requests a 1x1 pixel image from our server, once the request is validated the visit is counted in our logs.

Some customers are sceptical about the performance, they claim that it takes too long to do this request since a connection to another server has to be made.
I am aware that performance varies with time of day and else but I am trying merely to establish a range of how long it takes to request our script. I came across a software websimulator from xat.com, which would do the job but unfortunately, since the image is embedded in a javascript it is not listed separately in the log.
If somebody knows another way to measure downloadtimes this would help a lot.

I see what you mean. Standard server logs can include a "time-taken" field that shows in milliseconds the time taken to process the request. Not sure how useful/accurate this is...
