Thread: [IMPORTANT] - My application performance
My application is using Firebird 1.5.2 I have at my database: - 150 Doamins - 318 tables - 141 Views - 365 Procedures - 407 Triggers - 75 generators - 161 Exceptions - 183 UDFs - 1077 Indexes My question is: Postgre SQL will be more faster than Firebird? How much (in percent)? I need about 20% to 50% more performance at my application. Can I get this migratin to postgresql ?
The number of objects in your system has virtually nothing to do with performance (at least on any decent database...) What is your application doing? What's the bottleneck right now?

What's the your platform? Windows or Linux?
What's the data volume (up million records)?

Assunto: [PERFORM] [IMPORTANT] - My application performance
My application is using Firebird 1.5.2
I have at my database:
- 150 Doamins
- 318 tables
- 141 Views
- 365 Procedures
- 407 Triggers
- 75 generators
- 161 Exceptions
- 183 UDFs
- 1077 Indexes
My question is:
Postgre SQL will be more faster than Firebird? How much (in percent)?
I need about 20% to 50% more performance at my application.
Can I get this migratin to postgresql ?

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match

How much (in percent)? I think you can probably expect around 10341.426% improvement. ps. Yes, I am joking just in case...

The answer is: maybe. There's nothing which stops PostgreSQL from
being faster, and likewise there is nothing that stops it from being
slower. YMMV.
Your route should be:
* migrate most speed-demanding part to PostgreSQL
* benchmark it, trying to emulate real-world load.
* if it is slower than Firebird, post it here, together with EXPLAIN ANALYZEs
and ask if there's something you can do to speed it up.
