<h3>Optimizing 3proxy for high load</h3>
<p>Precaution 1: 3proxy was not initially developed for high load and is positioned as a SOHO product, the main reason is "one connection - one thread" model 3proxy uses. 3proxy is known to work with above 200,000 connections under proper configuration, but use it in production environment under high loads at your own risk and do not expect too much.
<p>Precaution 2: This documentation is incomplete and is not sufficient. High loads may require very specific system tuning including, but not limited to specific or cusomized kernels, builds, settings, sysctls, options, etc. All this is not covered by this documentation.

any application which performs IOCTLS), use -s0 option to disable splice() usage for given service e.g.

There are known race condition issues in Linux / glibc resolver. The probability

Довольно часто перед системным администратором встает задача предоставить доступ к Internet-ресурсам группе пользователей (небольшой офис, Internet-кафе). Данную задачу можно решить, настроив на Internet-шлюзе proxy-сервер, службу NAT (трансляция сетевых адресов) или раздать каждому пользователю реальный IP адрес.

Давайте рассмотрим самый простой способ подключения - установку proxy-сервера. Традиционно для этих целей применяется популярный proxy Squid, но не всегда бывает необходимость в столь тяжеловатой программе :), да и в squid отсутствуют такие иногда необходимые вещи как SOCKS4/5-сервер, TCP/UP порт-маппинг. Поэтому вторым номером хочется представить вашему вниманию PROXY-сервер, под названием "3proxy" (http://3proxy.ru/), разработанный нашим программистом из г. Нижний Новгород. Одним из главных его достоинств является компактность и высокая переносимость. Код сервера написан так, что легко компилируется как для Win9x/2000/XP так и для Linux и FreeBSD.

К недостаткам можно отнести отсутствие кэширования информации :-|. Но в последнее время Inernet-контент становится все более динамичным (то есть не поддающийся кэшированию) и может быть для кого-то экономия в 25% трафика за счет его кэширования не будет столь критична.
