All,
I have a table with ~ 3 million records. I'm indexing a field holding names, no more than 200 bytes each. Indexing the resulting tsvector takes forever. It's been running now for more than 40 hours on a Linux with PG 8.01, a single Xeon & 4GB RAM. My work_mem postgresql.conf parameter is at 240960 and maintenance_work_mem at 96384, although the index task is using at most 12MB. Task is 99% cpu bound. Is there any way I may speed up the indexing?
What's your tsearch2 configuration ? Do you use dictionaries ? I wrote a brief explanation of tsearch2 internals http://www.sai.msu.su/~megera/oddmuse/index.cgi/Tsearch_V2_internals
Hope, it could help you.
TIA,
