Re: Windows performance

There are some differences that I haven't mentioned.
Postgres on Linux is PostgreSQL 9.1.4 64 bit
Postgres on Windows is PostgreSQL 9.5.0, compiled by Visual C++ build
1800, 64-bit

The query is very big but I pasted it at the end of the mail with the
EXPLAIN ANALYZE.
I runned the queries many times on every machine, the cache is not
involved.

postgresql.conf are defaults, I haven't compared them yet but I will.
