From: Dyr, Dennis Yusupoff <dyr@homelink.ru.> Newsgroups: email Date: Mon, 25 Apr 2006 14:31:37 +0000 (UTC) Subject: Тестирование производительности MySQL на DualCore процессоре под FreeBSD 6.0 Тестирование производительности MySQL на DualCore процессоре под FreeBSD 6.0 Решил протестировать производительность MySQL на разных машинах и под разными условиями. Поскольку тема эта весьма обьёмная, тестирование разбито на несколько частей. Итак, сегодня тестирование MySQL 5.0.20 и влияния на него двухядерности процессора. Сервер: CPU Intel Pentium D 820 (2,8GHz DualCore) MB IntelR Server Board SE7230NH1-E (LX Version) RAM 2x1Gb DDR2 ECC HDD 1x200Gb Seagate 7200.8 SATA Методика тестирования: Тестирование производится с помощью утилиты SysBench, с последовательным увеличением количества потоков в арифметической прогрессии. Запуск утилиты производится три раза, данные усредняются. Включение и выключение SMP осуществляется путём изменения machdep.hyperthreading_allowed. Применявшийся скрипт для тестирования: #!/bin/sh table_type=innodb #table_type=myisam sysbench --num-threads=1 --max-time=60 --test=oltp --mysql-table-type=$table_type\ --db-driver=mysql --mysql-user=root --oltp-read-only=on cleanup > cleanup sysbench --num-threads=1 --max-time=600 --test=oltp --mysql-table-type=$table_type\ --db-driver=mysql --mysql-user=root --oltp-read-only=on prepare > prepare for a in "on" "off"; do for t in 1 2 4 8 16 32 64; do echo "Now testing $table_type table type with --oltp-read-only=$a and --num-threads=$t" sysbench --max-requests=5000000 --num-threads=$t --max-time=60 \ --test=oltp --mysql-table-type=$table_type --mysql-user=root \ --oltp-read-only=$a run done; done; Значения количества потоков выше 64 не поддерживались MySQL. Результаты: Таблица результатов:

Графики результатов:

Выводы: Использование второго ядра у Intel Pentium D под FreeBSD влечёт за собой уменьшение производительности MySQL при работе с выборками из таблиц при количестве одновременных процессов до восьми и увеличении производительности при дальнейшем увеличении этих процессов. Причём увеличение количество транзакций прямо пропорционально увеличению количества параллельных процессов.

В топку таких читателей, которые не знаю, что до FreeBSD 6.1 включение использования второго ядра(при скопмиленном ядре) на интеловских процессорах происходит именно так. Сам найдёшь, где прочитать, или подсказать?

Шутишь?
