The use or overuse of nested tables (tables within tables within tables) can cause significant delays because tables render from the inside out and typically the innermost table is the lowest in the html. This is even more noticeable if the size of the table is not set properly (you will see things blinking in and out).

A second contributor is images without their size set. This is because the tables don't know how much space to leave for them so the tables must keep readjusting their size and content as images come in. Combine this with the nested table issue and you have some good delays happening.
