The v2.1.4 snapshot seems to have made a very big difference in certain types of queries (esp.against blobs as per Alan).
Before, issuing a query like this (against ~13,000 records):
select contact.name,contact.firstname,contact.lastname, companycontact.* from companycontact
inner join contact on (companycontact.contactid=contact.id)
where ( (UPPER(companycontact.notes) LIKE '%AND%') )
made the FBServer process go from 20k to 250k. Whereas now it increases to just 29k. In some situations we could just watch it rise into the gigs. Task Manager stats may not be the most reliable and I am not knowledgeable enough about some of these things but wanted to share in case it can help others.
