Kevin, thanks for your attention!
I've read SlowQueryQuestions, but anyway can't find bottleneck...
Here requested information:
OS: Ubuntu 9.10 64bit, Postgresql 8.4.2 with Postgis
Hardware: AMD Phenom(tm) II X4 945, 8GB RAM, 2 SATA 750GB (pg db
installed in software RAID 0)
Please also note that this hardware isn't dedicated DB server, but
also serve as web server and file server.
I have about 3 million rows in core_object, 1.5 million in
plugin_plugin_addr and 1.5 million in plugins_guide_address.
When there were 300 000+ objects queries works perfectly, but as db
enlarge things go worse...
# select version();

I hope this help!
Any ideas are appreciated!
