Hello list,

I've been testing tsearch2 for a while and I recently noticed some really slow queries.

This is a quite big document so the times are maybe accurate.

The document has about 194 000 words.

I put all the data in tbl_fulltext.fulltext_text and then did a

update tbl_fulltext set vectors = to_tsvector(fulltext_text);

Which takes about 80 seconds to complete.
The hardware is a Pentium 4 2.8GHz with 1GB HyperX memory.

Is this normal? What can I tweak in postgresql.conf to speed up big to_tsvector()?

What is your configuration ? to_tsvector does a lot of work.


Regards,
Henrik
