I found a monster spawner on my SMP server and built a trap underneath to kill skeletons and move the loot into another room. Does the server run this area at all times? Even when there aren't any players in there? It's deep down near bedrock.
the server only loads chunks the player loads. If you can see it then its loaded. when you unload the chunks (by moving away from them) the server will unload chunks and de-spawn mobs.
Consider night time when you're dealing with 600 mobs populated in the chunks loaded around a single player - even this doesn't generally lag a server. You'll be fine with even HUGE mob spawners.
