Subject Re: SolrCloud different machine sizes

"It Depends"(tm). As long as you're getting adequate
throughput on the smaller machines, adding bigger
machines won't make it any _slower_. But sometime
as you add documents, the smaller machines will start
having memory issues etc. and you will see an impact.

Fortunately, the migrating path to larger machines is
pretty painless.

2> wait for them to synch up and start serving queries
3> shut off the smaller machines.
