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()?
Regards,
Henrik
