Facet Search is too slow ! Optimize suggestions ?

Hello.

I use facet-search for my autosuggestion. the results are okay, but
sometimes its toooooo slow.

We Have 4,2 Million Documents and each day we get more and more ... I try
out the Cache Settings with this parameter:

<filterCache
      class="solr.FastLRUCache"
      size="2000000"
      initialSize="1000000"
      autowarmCount="80"/> 

For every Cache. How can i optimize the facet search ? 
The Server is an 8 Dual Core with .. i think 12 GB RAM ... so i thought
thats enough for Solr Facet search. 

When a new Search search for something like: "rotw" and nothing is cached
solr need sometimes much time for a response ... =( =(  all over two seconds
is not good fur autosuggestion ...

thxxx

My initial thought is that cache size is way too big, but before we get into that, can you tell us more about
your app?  What are you faceting on?  How are you faceting on it?  How many unique terms?
