A Very Bad Bug

Jira report SVC-3867 points to a very bad bug that, when fixed may well result in lower lag across the board and perhaps a tremendous lag reduction in some sims. Although as yet no one has a repro, what's going on is that in some cases (at the moment random-seeming as in ghost prims) a scripted object is deleted but its scripts keep on running.

Island owners and managers have seen cases where an item was removed because its script was lagging the sim. After removal no change was observed and in fact the script could be viewed in island management tools. If a ghosted script is targeted by beacon, and then removed that way even though it isn't visible or meant to be there, it will finally be gone, I think, but that's a tricky line to follow on a busy island, and one that mainland owners with no management tools are not able to emulate.
