Pesquisando o desempenho do DBMS MS SQL Server Developer 2016 e PostgreSQL 10.5 para 1C

1. postgresql.conf:
   As configurações básicas foram feitas usando a calculadora - pgconfigurator.cybertec.at , os parâmetros Huge_pages, checkpoint_timeout, max_wal_size, min_wal_size, random_page_cost alterados com base nas informações recebidas das fontes mencionadas no final da publicação. O valor do parâmetro temp_buffers aumentou, com base na sugestão de que 1C usa ativamente tabelas temporárias:
   
   

   listen_addresses = '*' max_connections = 1000 #     .          .    32     25%    . shared_buffers = 9GB #   (  Linux - vm.nr_hugepages). huge_pages = on #      . temp_buffers = 256MB #      ORDER BY, DISTINCT, merge joins, join, hash-based aggregation, hash-based processing of IN subqueries. #  ,  1     ( "Mostly complicated real-time SQL queries"  ).     64MB. work_mem = 128MB #    . VACUUM,  , etc. maintenance_work_mem = 512MB #    (vm.dirty_background_bytes, vm.dirty_bytes),        IO   CHECKPOINT. checkpoint_timeout = 30min max_wal_size = 3GB min_wal_size = 512MB checkpoint_completion_target = 0.9 seq_page_cost = 1 #   .  - - 4.  RAID10  . random_page_cost = 2.5 #       postgres ,    PageCache. effective_cache_size = 22GB 

   
   
2. Kernel, parâmetros do SO:
   
   As configurações são definidas no formato de arquivo de perfil para o daemon ajustado:

 # ----------------------------- # PostgreSQL configuration file # ----------------------------- # # This file consists of lines of the form: # # name = value # # (The "=" is optional.) Whitespace may be used. Comments are introduced with # "#" anywhere on a line. The complete list of parameter names and allowed # values can be found in the PostgreSQL documentation. # # The commented-out settings shown in this file represent the default values. # Re-commenting a setting is NOT sufficient to revert it to the default value; # you need to reload the server. # # This file is read on server startup and when the server receives a SIGHUP # signal. If you edit the file on a running system, you have to SIGHUP the # server for the changes to take effect, run "pg_ctl reload", or execute # "SELECT pg_reload_conf()". Some parameters, which are marked below, # require a server shutdown and restart to take effect. # # Any parameter can also be given as a command-line option to the server, eg, # "postgres -c log_connections=on". Some parameters can be changed at run time # with the "SET" SQL command. # # Memory units: kB = kilobytes Time units: ms = milliseconds # MB = megabytes s = seconds # GB = gigabytes min = minutes # TB = terabytes h = hours # d = days #------------------------------------------------------------------------------ # FILE LOCATIONS #------------------------------------------------------------------------------ # The default values of these variables are driven from the -D command-line # option or PGDATA environment variable, represented here as ConfigDir. #data_directory = 'ConfigDir' # use data in another directory # (change requires restart) #hba_file = 'ConfigDir/pg_hba.conf' # host-based authentication file # (change requires restart) #ident_file = 'ConfigDir/pg_ident.conf' # ident configuration file # (change requires restart) # If external_pid_file is not explicitly set, no extra PID file is written. #external_pid_file = '' # write an extra PID file # (change requires restart) #------------------------------------------------------------------------------ # CONNECTIONS AND AUTHENTICATION #------------------------------------------------------------------------------ # - Connection Settings - listen_addresses = '*' # what IP address(es) to listen on;
