Linux TCP 系统参数配置

1)low:当TCP使用了低于该值的内存页面数时，TCP不会考滤释放内存。2)pressure:当TCP使用了超过该值的内存页面数量，TCP试图稳定其对内存的占用，进入pressure模式,直到内存消耗达于low值，退出该模式。3)hight:允许所有tcp sockets用于排队...

Linux系统TCP内核参数优化总结

日常运维工作中，会遇到很多TCP相关的问题，网上有很多文章介绍需要优化哪些TCP内核参数，但是并没有很详细说明优化的依据、适用的场景是什么，如果我们不了解各个参数实际的作用，照搬网上的配置到生产环境，很有可能会适得其反，本文从...

优化Linux下的内核TCP参数以提高系统性能

在Squid服务器中可输入查看当前连接统计数的命令，如下所示：netstat-n|awk '/^tcp/{+S［$NF］} END {for(a in S)print a,S［a］}' LAST_ACK 14 SYN_RECV 348 ESTABLISHED 70 FIN_WAIT1 229 FIN_WAIT2 30 CLOSING 33 TIME_WAIT 18122 ...

Linux集群和自动化维1.4.2 优化Linux下的内核TCP参数以提高系统性能

1.4.2 优化Linux下的内核TCP参数以提高系统性能内核的优化跟服务器的优化一样，应本着稳定安全的原则。下面以Squid服务器为例来说明，待客户端与服务器端建立TCP/IP连接后就会关闭Socket，服务器端连接的端口状态也就变为TIME_WAIT了。那...
