Hello, i have a problem between V7.4.3 Cygwin and
V8.0RC2 W2K. I have 2 systems:
1. Production Machine
- Dual P4 3000MHz
- 2 GB RAM
- W2K
- PostgreSQL 7.4.3 under Cygwin
- i connect to it over a DSL Line
2. Develop Machine
- P4 1800MHz
- 760 MB RAM
- PostgreSQL Native Windows
- local connection 100MB/FD
Both systems use the default postgresql.conf. Now the problem.
I have an (unoptimized, dynamic) query wich was execute on the
production machine over DSL in 2 seconds and on my develop
machine, connected over local LAN, in 119 seconds!
Whats this? I can not post the query details here public, its a commercial
project. Any first idea? I execute on both machine the same query with
the same database design!
