Nice to get the very first response from you :-)

Increasing the scalability of the SPARQL endpoint is a function of:

1. Actual Virtuoso instance (we currently use the Single Server Open 
Source Edition rather than the Commercial Cluster Server Edition)
2. Controls deliberately put in place on the server side to protect the 
public endpoint e.g. queries generating large result sets etc..
3. Reality of Web Scale (the public endpoint is just that a free public 
endpoint on the Web, you need a service specific variant for your varied 
SLA type requirements hence the creation of DBpedia AMIs [1]).

-- this is how you can set up your own service specific rendition of 
DBpedia. There will be a Cluster Edition of this available very soon.
