Ok, so I assume WMPS (WebMap Publisher Service) is used to provide the data.

One thing worth remembering is that authoring the label placement rules in the Label Rule File so that they allow for greater flexibility of placing labels bogs performance down. The engine tries its best at displaying the maximum number of labels it can fit in the visible area according to the rules. If, for example, you allow for font downsizing, the engine first tries to place all labels with the original font size. Then, it determines the colliding labels and restarts the placement process with selectively applying a smaller font size to them. With multiple features to label and other options allowing more wiggle room for the engine, you can see this can quite intense pretty quick.
For dynamic labeling to work fast, it's best to limit the number of possibilities for the labeling engine to account for. Very important labels that decidedly should be in the output image, are best done using static labels (textpoint feature classes work the fastest). Using dynamic labeling for such labels is asking for trouble, performance-wise.
Maybe you'd like to share the LRF you use as well?
