Subject: [GENERAL] Windows performance
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.
More details would be helpful:
- PG version
- PG config on both servers
- Actual query you are using
Regards,
Igor Neyman
