Доброго времени суток уважаемые форумчане.
бьюсь с проблемой уже около месяца, я даже не знаю куда копать.
Суть такова, есть 2 машины, Мускул и Веб, между ними 1gb\s канал.
Сайт открывается секунд по 5, если отключить запросы к мускулу (или перенести сайт на машину с мукулом) то сайт начинает летать. Любые запросы от локалхоста мускул выполняет очень быстро, любые запросы с локальных IP начинает тормозить.
Между машинами пинг =1мс, Файлы я качаю по 50мб\с, а дамп базы выполняется дай бог о скоростью 10кб\с
не могу понять чем вызваны такие тормоза (((.
Таже проблема наблюдается с доступом по SSH к самой удаленной машине. так что мб дело совсем не в мускуле ??

# The MySQL database server configuration file.

# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

# For explanations see
