Investigating Slow Loads
From PluginWiki
If you find your page is taking a long time to load, you can do some investigation of it instead of Getting Debug Trace.

What you need
To do this, you need the Tamper Data plugin. Get it here.
How to use it
Once you have Tamper Data installed, start it up from Tools->Tamper Data. You'll get a window which shows the requests Firefox is making. It looks a bit like this:
The key two columns here are Total Duration and URL. You might need to resize the columns to make them visible - you can do this by dragging the dividing lines next to the column titles.
In the Total Duration column, you'll see a number. This can be one of two things:
- A number, which is the number of milliseconds it took to process.
- 0, which generally means that Firefox has made a request and it hasn't completed yet. Some requests, often to yimg.com addresses, will always show up with 0, which you can ignore.
What happens when Yahoo's slow
When Yahoo's going slowly:
- What you'll see is requests which stay at 0, i.e. never complete.
- The URLs involved may give you some indication of particular things that are going slowly. Please try to identify patterns in the URLs. If you can't see any patterns, it's probably just general Yahoo slowness.
Sending the information
You can export this data by right-clicking and selecting Export XML -> All if you need to send it to Edward - but please try to identify patterns yourself first.
Please send a screenshot too with as much of the URL visible as possible, since that makes it easy to see the slow requests.
Exports contain confidential data, so be careful who you send them to.
