Ctrl - Shift - 3.....................

I tend to use this alot when I log in to work out how fast the textures are downloading. I think this gives me a good idea of fast SL is running at that point in time and how good my connection to it is.

One question....

What are the colour codes?
Some textures come down as white, some pink and I even get the odd yellow. Are the colours significant ?

Try Ctrl+Shift+9 for a mind boggling array of colours

Actually, for those with the time, it gives excellent reporting between the client and the sim servers etc. I use some of it, when determining if the sim is too buggy for machinima or movie playing.
