RF Plan 'Locate' speed

I'm finding that whenever I try to locate a client or rogue AP, the plan hangs for up to 5 minutes. When it is eventually displayed the refresh (default 10 seconds) kicks in before you can do much and the page hangs again.
Has anyone had this kind of performance problem before? We have 1 master and two local controllers - all a6000 models, with 12 floor plans in place and 237 APs currently deployed.
It does not matter which web browser or machine I try from, the same results occur, effectively rendering the RF plan tools useless.
