Hello.
I have a Primergy TX100 S1 server, with runs very slow with Firebird 2.5. I have done the next test and configurations:
- Centos 6.2 64 bits with ext4 filesystem and Firebird 2.5 AMD64, firebird database on 2.5 structure (8192 page size): very slow.
- Centos 6.2 64 bits with ext4 filesystem and Firebird 2.5 SS (32 bits), firebird database on 2.5 structure (8192 page size): very slow.
- Centos 6.2 32 bits with ext4 filesystem and Firebird 2.5 SS/CS (tested with both), firebird database on 2.5 structure (8192 page size): very slow.
- Centos 6.2 32 bits with ext3 filesystem and Firebird 2.5 SS/CS, firebird database on 2.5 structure (8192 page size): very slow.
And finally:
- Centos 6.2 32 bits with ext4 filesystem and Firebird 1.5.6 SS , firebird database on 1.5 structure: runs very well.
As test says: firebird 2.5 on linux is very slow, and slower than 1.5.6.
I can't belive it. Perhaps I have something wrong in my configuration? I don't change firebird.conf parameters.
Where could be the problem?
