I've got a simple query. When I use explain analyze it lasts 7 times slower.

You've got a machine where gettimeofday() is really slow.  This is

I'd be curious to know more about the hardware and operating system Szymon is using if you suspect this is the case.  I keep hearing about systems where this is slow, but despite claims that they're common I've never actually seen one.
