postgres/contrib/fulltextindex/BENCH

The following data was generated by the 'timings.sh' script included
in this directory. It uses a very large table with music-related
articles as a source for the fti-table. The tables used are:

product    : contains product information  :   540.429 rows
artist_fti : fti table for product         : 4.501.321 rows
clustered  : same as above, only clustered : 4.501.321 rows 

A sequential scan of the artist_fti table (and thus also the clustered table)
takes around 6:16 minutes....

Unfortunately I cannot probide anybody else with this test-date, since I
am not allowed to redistribute the data (it's a database being sold by
a couple of wholesale companies). Anyways, it's megabytes, so you probably
wouldn't want it in this distribution anyways.

I haven't tested this with less data.

The test-machine is a Pentium 133, 64 MB, Linux 2.0.32 with the database
on a 'QUANTUM BIGFOOT_CY4320A, 4134MB w/67kB Cache, CHS=8960/15/63'. This
is a very slow disk.

The postmaster was running with:

        postmaster -i -b /usr/local/pgsql/bin/postgres -S 1024 -B 256 \
                -o -o /usr/local/pgsql/debug-output -F -d 1 

('trashing' means a 'select count(*) from artist_fti' to completely trash
any disk-caches and buffers....)
