Shopper Administration Filter Selection Pegs CPU

[leighjam]

When on the shoppers administration page if the filter dropdown is moved from  "only joomla" to all. Any filter request will hang the server.  Specifically MySQL attempts to pull such a large data set that it hangs the server (on a 6 CPU system it was at CPU 300%)  After restarting Apache and MySQL everything returned to normal. 

Is there a purpose for this option or can it be disabled as an 'accident' can cause serious problems?

Thanks!

That is the reason we have the option. It searches then all addresses. I am very interested to find the performance problem here.
