Performance profiling a .net website with shared,r

问题:

Having performance issues with my website. I'm relatively new to .net, although I've learned an awful lot over the last few months!

I posted this question last night

Improving performance when working on Images with ASP.NET in VB

From which a comment was posted which got me thinking, and Googling this morning.

I'm unclear on how I would actually got about 'performance profiling' my site.

I've seen that there are tools built into visual studio if I can replicate the entire site locally, but I can't do that. There are also tools in iis, and this:

I like the look of the screen shots on the link above, it seems intuitive and easy to understand.

What I am totally unclear on though is, does require direct access to the actual server machine? Or, is it a .net plugin which I can use remotely.

I need this facility because the site is hosted on a shared server which I do not have direct access to.

If this isn't the case, does anyone have any suggestions as to how to go about finding bottlenecks in my code, remotely?

Quickest way I know is to install FireBug for Mozilla Firefox and take a look at the net tab while the page is loading. This displays a clear timeline of server calls and loading time taken. https://getfirebug.com/

Taking a quick look at your site with Firebug shows each image taking nearly a second to load for me. It could be that your ISP is just slow, who are you hosting with?
