Andrew,

Thanks for your comments.

I can assure you that we have plenty of bandwidth (both in the front
door, and between the tiers), and nothing in the site is breaking into a
sweat! We have a DBA on staff who looks at optimisation regularly.

Hi,

Nooooooo. You should not standardise on one type of images. jpg should
be used=20
for photo's and images with lots of colour and shades. gif's should only
be=20
used for things like buttons, with a limited amount of colours, say 16
or so.

With jpgs, you cannot restrict the colour palette and the compression is

optimised for using 16m colours.

With Gifs you CAN restrict the colour palette and the header of the file
says=20
which colours are being used, then if you are using black white and red
in a=20
button, you are only using 3bits per pixel. This way we get some of our
buttons=20
on our websites down to around 100bytes!

I gave my sister a crash course on this. She had some photos on her
website as=20
gifs and the were about 850kb, when I converted them to jpgs got them
down to=20
about 120kb, still big, but it's not going to bugger modem users.

I could go on but...

Now for the b&q site.

Page weight is fine, about 40kb, big but should not be taking that long
to=20
download.

The only things that could be making this page load so slowly are:

Limited Bandwidth (either physically or server related).
Backend (i.e. Databases)

if you have plenty of bandwidth and the servers are not overloaded and
things=20
are still looking bad, check the optimisation of the backend DB.

I am assuming all the lefthand nav and the content in center are driven
by a=20
cms of some description.

I managed to optimise the home page of www.ecardsforyou.co.uk from
taking about=20
20sec down to .25sec for the first page impression.

These speeds are all render time at the webserver, not physical download
to a=20
browser of course, some poor soul still using a 1.44k modem will still
be=20
waiting some time. :-)
