Hello

Why is Postgres so slow on Windows compared to linux?
Can I do something to match the performance?
I have 2 servers:
- one is Windows 8, CPU XEON, 8 CORES, 32G of RAM - my test query runs
in 17 seconds
- the other is Linux CPU XEON, 4 cores, 4 Gh of RAM - my test query runs
in 2 seconds
I run the query on the same database.

CPU is not used at max on the servers, RAM is fine.
Is there a problem with Windows? My gues is that Windows is not using
the hardware resources as it should be.
Can I do something to fix this?

Thank you.
