Subject Performance regarding hard drive
Author Steffen Heil (Mailinglisten)

I am trying to figure out, how to configure my system to get good performance.
I am using
- Linux (kernel 4.12/4.14)
- Firebird 3.0.2 (3.0.3 soon)
- database files on ex4 volumes

For safety reasons I have
- mounted the filesystem with data=journal
- enabled forced writes in firebird

Now writing to the database is very slow, especially if the database is in backup mode and firebird is writing to a .delta file.

What in firebird.sql is important and what could I change (without risking data) to improve performance?
