The problem is with Publisher. I published the site before, & it is working
fine on the internet. Now I wanted to make edit. Since then the publisher
became very slow.

Solution: I found out the problem.
I had made a table for features, in which whatever feature is present, I
inserted a True tickmark image. Wherever the feature is Not available, I
inserted a picture of a false checkmark. there were 5 to 6 pages like these.
The moment I deleted these pages, i found out that publisher is working with
the same as before, full, speed.
So the problem was with publisher, that it takes too much time to process
pages with large number of images, even if the images are of 2KB size only.

Any comments are welcome.
Thanks
