Distributed Searching Index Size

[Dennis Kubes]

Does anybody have recommendations as to index size per machine using 
distributed searching.

We are currently doing about 1M pages per index with each index on a 
separate machine.  That seems work fast.  Just wanted to know what stats 
other people were using.

Also I thought I remembered seeing a post from Doug a while back about 
overall performance settings but couldn't find it, anybody know where 
that is?
