1C+Ubuntu против CentOS

[Borr]

В организации стоит 1с 8.2 на Ubuntu 10.04.4(ядро 2.6.32-42-generic-pae on i686, раздел на котором база ext4) PostgresQL-1C(сборки eterosoft) 8.4.4
Сам ПК Core Duo 7300 8Gb ОЗУ

В общем полтора года как-то работало - бухи вообще не жалуются, а вот с Управлением персоналом во многих местах тормоза(при чем не зависят от нагрузки - 1чел работает 10 или 20 разницы никакой). Все бы ничего да узнал я, что якобы на CentOS эта связка работает быстрее. Так ли это? Можно ли как-то оптимизировать Ubuntu?

Тест Гилева на сервере показывает 6,5 балов, а если пробую с локальным файликом аж 45. В общем можно ли как-то оптимизировать поделитесь опытом, пожалуйста.

Borr,
Наверное стоит показать нам выгрузку нагрузки, т.е. логи загрузки системы. Может вы в конфигурации БД выставили не правильные параметры, вот она и работает у вас не на все 100%.

[Borr]

я не понял, можете конкретизировать какие логи? загрузки самой системы или нагрузка на cpu, память, винт? Ubuntu ведет такие логи по умолчанию? где посмотреть я о таком не слышал и чем вести если не по умолчанию. все настройки сервера 1с брал от сюда

Borr,

разрядной ОС и самой БД.
конфиг БД, где все характеристики.
Пинг до сервера, когда тестируете.
Вывод нагрузки сервера, когда тестируете сервер.
И прочее, что я упустил.

мне нравится вот эта документация: http://www.gilev.ru/1c/81/postgresql/

[Borr]

да эту тоже читал
вот мой конфиг postgres

# -----------------------------
# 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, or use "pg_ctl reload".  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, e.g.,
# "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

Постгрес отказывается стартовать пришлось поставить 64MB 

[graddata]

Borr,
Значит попробуйте 2GB и прочее.
А также, прошу логи старта БД.

[Borr]

у меня там ничего такого нет кроме как orphan temp table от autovacuum.
Я параллельно связался с другими товарищами, они (повторили то же, что и Гилев) - рейд с независимым кешем и fsync=off. Пробовал еще autovacuum выключать - особой разницы не заметил. Кто-то в конце концов вообще ушел на MS SQL.
9.1.2, говорят, тоже проблему не решает.
К стати про CentOS вроде как слух - примерно то же самое. У меня к сожалению нет тех базы для экспериментов  .

Понятно.
В вашем случае, нужна более полная информация и не ровняться на этот тест, а смотреть, как реально работает сервер. Например, вывод top хотя бы.

В моменты тормозов надо показывать:

К стати про CentOS вроде как слух - примерно то же самое.

Неудивительно, ведь ФС и ядро те же самые, версии пакетов, скорее всего, тоже почти не отличаются.

[Borr]

там дело не в системе, а в нагрузке PSQL на диск (1С создает много временных таблиц много коммитов). Знающие люди вообще мне покрутили у виска, узнав, что я без рейда живу. Еще и удивились что у меня не везде тормозит.
