Usually, animations(the curtain animation most noticeably),animated textures and sprites will drive up your network load times as well as props that have the fade state applied. Those props with those scripts and states applied will appear red with high numbers, which is why one would use those sparingly. In and of themselves they wont stop you dead in your tracks by themselves, but if you add in mis sized textures throughout, you will seem like you are moving through mud in a layout. The measurement tool is a good tool to use when decoing as it will give you an idea as to the lag that may be evident to others that have less bandwidth with their internet connection or their graphic memory space.
