Xapian discuss - May 2011 - Xapian Index 253 million documents = 704G

Xapian Index 253 million documents = 704G

I just build my largest single Xapian index with 253 million unique
documents on single server using single hard disk, less that 8G RAM
and single processor 2.0 GHz. I do not see any search performance
decreases in searching my indexes between 100 million and 250 million,
which indicates a good scalability of Xapian and it looks like, I can
push it easily forwards 300 million documents on single Index.

number of documents = 253717716
average document length = 35670.3
document length lower bound = 1
document length upper bound = 181656
highest document id ever used = 253717716

total 704G
