Fast search for disabled Host Status check

What language are you using?

I'm not sure what groovyscript has available in the way of filtering, but if you can find a way to pre-filter your results, it'll have fewer iterations to do... that will reduce the time it takes to do so.  What are the conditions/properties you're sampling/matching for this task?  In powershell, you can grab the whole chunk of them, then pipe them through a where to reduce the found set to just the ones with specific hoststatii.. or at the least, exclude known good ones to allow the rest of the set to be tested.  If you're matching it agianst another set of objects, you can use the -includes comparison operator to do a faster comparison once you've gathered the test set and the comparison set.
