Hi,
we have loaded some 2500 fulltexts - journal articles and the tgz
packed archive is 500MB, the database itself, with everything + 100MB.
So the actuall numbers must be higher. (note, the fulltext are just
pdf with text, not pictures)

Could somebody with really a huge collection please share their
experience with the speed of fulltext indexing/searching?
