Native data types such as integer or real are much faster than numeric. If you need 6 digits, it's better to multiply your coordinates by 10^6 and store as INTEGER.
On my development server (dual proc/dual core Opteron 2.8 Ghz with 4GB ram) this query averages 1.5 seconds each time it runs after a brief warmup period. In PostGreSQL it averages about 15 seconds.
What hard drive(s) and controller(s) do you have? Please post EXPLAIN ANALYZE output of the problem query and your postgresql.conf also.
