Optimized Firebird configs (gratis)

Aqui encontrará arquivos de configuração do Firebird otimizados. Estas configurações são otimizadas para um hardware médio com uma carga média. Nós esperamos que estes arquivos de configurações melhorados ajudem a resolver muitos dos problemas típicos de performance com o Firebird.

Faça o download dos arquivos de configuração para a versão do Firebird em uso, copie-o para a pasta do Firebird, renomeie para firebird.conf e re-inicie o Firebird (todos os usuários ativos devem ser desconectados antes da reinicialização do Firebird). Sempre renomeie e mantenha uma cópia do seu arquivo firebird.conf original.

Se precisar de um arquivo de configuração otimizado para o seu ambiente específico, para obter a melhor performance possível ou se continuar com problemas de performance depois de utilizar os arquivos desta lista, por favor, contate-nos para obter suporte de otimização sob medida.

Firebird 3

Select the architecture and then select the configuration file:

SuperServer: If you have 1 main database and, optionally, 2-5 smaller (and less loaded) databases on the server, choose SuperServer architecture and configure each database in databases.conf.

• Firebird 3 SuperServer configuration for server with RAM 8-12Gb with 3 databases:
  • firebird_30_superserver_64bit_ram8gb.conf, databases_30ss_8gb.conf (only 64 bit)
• Firebird 3 SuperServer configuration for server with RAM 16-32Gb with 3 databases:
  • firebird_30_superserver_64bit_ram16gb.conf, databases_30ss_16gb.conf (only 64 bit)

SuperClassic: if you have many databases on the server (from 10 to 1000), and they are more or less equal in terms of load, and your application is stable (i.e., you never saw “Abnormal termination” in firebird.log), choose SuperClassic. It is better than Classic in terms of better control of sorting memory and performance

• Firebird 3 SuperClassic configuration for server with RAM 8-12Gb with 10+ databases with 150 connections for all databases totally:
  • firebird_30_superclassic_64bit_8Gb.conf (only 64 bit) 
• Firebird 3 SuperClassic configuration for server with RAM 16-32Gb with 10+ databases with 300 connections for all databases totally:
  • firebird_30_superclassic_64bit_16Gb.conf (only 64 bit)

Classic: if you have many databases (from 10 to 1000) on the server and they can be problematic in terms of stability, or if you have 32bit UDF, choose Classic.

• Firebird 3 Classic configuration for server with RAM 8-12Gb with 10+ databases with less than 150 connections totally:
  • firebird_30_classic_32bit_8Gb.conf 32bit,
  • firebird_30_classic_64bit_8Gb.conf 64 bit
• Firebird 3 Classic configuration for server with RAM 16-32Gb with 10+ databases with less than 300 connections totally:
  • firebird_30_classic_32bit_16Gb.conf 32bit,
  • firebird_30_classic_64bit_16Gb.conf 64 bit

Firebird 2.5

Select the architecture and configuration file:

SuperServer: if you have 1-2 database with small load (1-3 simultaneously active users, up to 20 users totally), and limited hardware resources, choose SuperServer.

• Firebird 2.5 SuperServer for server with RAM 4+Gb
  • firebird_25_superserver_32bit_4gb.conf 32 bit,
  • firebird_25_superserver_64bit_4gb.conf 64 bit

SuperClassic. This is the recommended architecture for Firebird 2.5. Choose it if you have stable applications (without “Abnormal termination” messages in firebird.log).

• Firebird 2.5 SuperClassic configuration file for server with RAM 8-12Gb, up to 150 connections totally:
  • firebird_25_superclassic_64bit_8gb.conf (64bit only)
• Firebird 2.5 SuperClassic configuration file for server with RAM 16-32Gb, up to 300 connections totally:
  • ​firebird_25_superclassic_64bit_16gb.conf (64bit only)

Classic. If you have applications with stability problem, or you are using 32bit UDF, choose Classic.

• Firebird 2.5 Classic configuration file for server with RAM8-12Gb, up to 150 connections totally:
  • firebird_25_classic_32bit_8gb.conf 32 bit,
  • firebird_25_classic_64bit_8gb.conf 64.bit 
• Firebird 2.5 Classic configuration file for server with RAM16-32Gb, up to 300 connections totally:
  • firebird_25_classic_32bit_16gb.conf 32 bit,
  • ​firebird_25_classic_64bit_16gb.conf 64.bit

How to proceed

Download configuration files for your Firebird version, copy it to Firebird folder, rename to firebird.conf and restart Firebird (all active users should be disconnected before Firebird restart). 
If you intend to change the architecture of Firebird (from SuperServer to SuperClassic, for example), please read the appropriate documentation first.

For all architectures – make sure you don’t override page buffers value in the header page of your database!
To ensure it, run gstat -h databasename and check that Page Buffers is 0. If it is set to other value, set it to 0 with command gfix -buff 0

Important!

• Always rename and keep a copy of your original firebird.conf and, for Firebird 3.0, databases.conf!
• For Firebird 3.0, always check databases.conf! There should be the values you explicitly set. Please make sure you understand why do you set them.
• Remember: settings from firebird.conf are applied to ALL active database on the server as default values, databases.conf (in 3.0) can override firebird.conf.
• Don’t forget about general OS tuning: see Short performance checklist

Optimized configuration files for discontinued versions of Firebird: 1.5, 2.0, 2.1

For discontinued versions of Firebird, we also provide update configurations files, but we really recommend to migrate to the modern Firebird version.
