Do you experience the same slow speeds when you manually issue those
queries? In other words, is it repeatable? If so, try
&debugQuery=true and see the component timings and where the time is
going.
What's the query parsing too? Anything unusually large due to synonym
lists or something like that?
What about your filter cache - how's it looking when these slow
queries take place? evictions > 0?

What's the config of your dismax handler look like?
