市场更新迭代，CPU也从很久之前的I5更新至今的I9 9900K，那么这个CPU性能如何呢？可以说快快网络I9 9900K性能多20%，比如：厦门BGP，稳定的机房比什么都重要。
小tips，当网站出现502问题时，该怎么解决呢？
1、查看当前的PHP FastCGI进程数是否够用netstat -anpo | grep “php-cgi”| wc -l 如果实际使用的“FastCGI进程数”接近预设的“FastCGI进程数”，那么，说明“FastCGI进程数”不够用，需要增大。
2、部分PHP程序的执行时间超过了Nginx的等待时间，可以适当增加nginx.conf配置文件中FastCGI的timeout时间。如果php.ini中memory_limit设偏低，修改php.ini的memory_limit为64M，重启nginx，说明PRH内存不足。
3、max-children和max-requests 一台服务器上运行着nginx php（fpm） xcache，访问量日均300W pv左右经常会出现这样的情况：php页面打开很慢，cpu使用率突然降至很低，系统负载突然升至很高，查看网卡的流量，也会发现突然降到了很低。一般这种情况只持续数秒钟便可恢复。
总之快快网络厦门I9 9900K，还是BGP线路，适用于企业以及个人，7*24小时售后时刻守护您。

TCP攻击是什么？有什么防护方式？
随着网络的高速发展，越来越多的企业都将业务部署在线下机房或者云上。随之而来的就是各种各样的网络攻击，如DDoS攻击、CC攻击、TCP攻击等，这些攻击对业务的影响也是很大。市面上有很多安全厂商都有研发出DDoS高防产品、CC防御产品，但是对于TCP攻击的防护不是特别的理想。那么，TCP攻击是什么？有什么防护方式？TCP攻击是什么？TCP攻击是指利用TCP协议中的漏洞或者缺陷对网络进行攻击的行为。这种攻击方式可以导致网络中的设备不可用，从而影响正常的网络通信。TCP攻击包括SYN Flood攻击、TCP Reset攻击、TCP Session Hijacking攻击等等。这些攻击方式常常被黑客用来发起分布式拒绝服务（DDoS）攻击。SYN Flood攻击是TCP攻击的一种形式，它利用TCP协议中三次握手的过程，向目标服务器发送大量的TCP连接请求。由于这些请求都是虚假的，服务器在回应这些请求时，需要耗费大量的CPU和内存资源，从而导致服务器无法响应正常的网络请求。 TCP Reset攻击则是利用TCP协议中的RST（reset）标志位，向服务器发送虚假的TCP连接请求。当服务器收到这些虚假的请求时，会断开与客户端的连接。这种攻击方式可以导致服务器中断正常的网络通信。 TCP Session Hijacking攻击则是利用TCP协议中的漏洞，获取正在通信的两个主机之间的会话ID，然后通过伪造的TCP数据包向服务器发送虚假的请求。当服务器收到这些虚假的请求时，会认为它们来自于已经认证的主机，从而给予响应。这种攻击方式可以让攻击者获取敏感信息，例如登录凭证等等。为了防止TCP攻击，网络管理员可以采取以下措施：1、加强网络安全措施：例如在网络边界处安装防火墙，限制网络流量，限制访问等等，以保护网络的安全；2、安装防御系统：例如入侵检测系统（IDS）和入侵防御系统（IPS），可以对网络流量进行实时监测，并对异常流量进行拦截和处理；3、更新网络设备：网络管理员应该定期更新网络设备上的操作系统和应用程序，以确保它们能够及时地修复已知的漏洞和缺陷；4、应用过滤规则：可以通过过滤规则，限制来自特定IP地址和端口的TCP连接请求，从而减少网络中的异常流量。TCP攻击是什么？有什么防护方式？总之，TCP攻击是一种危害性较大的网络攻击方式，可以导致网络设备不可用，影响正常的网络通信。网络管理员应该加强对网络的安全管理，采取必要的防御措施，以保护网络的安全。快快网络的高防服务器如扬州BGP、厦门BGP、宁波BGP、台州BGP等机房服务器，针对TCP攻击都自带有防护体系，可以更好地防护TCP攻击、DDoS攻击等，详询快快网络舟舟（QQ：177803618），快快网络--新一代云安全引领者！

快快网络厦门BGP怎么样
快快网络新上产品-厦门BGP。目前该bgp是三线bgp包含了电信线路、网通线路、移动线路。网络稳定性高达99.9%是福建省最大的T5级机房。极度适合企业客户、网站类、软件开发类、小游戏、app等业务。目前厦门bgp也承接托管。欢迎实地考察，厦门地区免费专车接送。 厦门BGP具体好在哪里呢？首先厦门bgp实现了真正的三线bgp，包含了电信网通移动。 关于BGP线路服务器的优势主要有以下几点： 优势一：可智能切换至最佳线路，保障网络稳定BGP可以智能的判断服务器端和客户端的状态，并自动选择最快的带宽来去提高连接速度，使访问者能接入到最优质的的线路中进行访问。一旦出现线路故障，例如单一线路故障时，BGP线路可以自动将用户转接到其他正常的线路上去访问。 优势二：解决南北不互通问题，实现跨运营商快速访问国内主机访问速度慢的一个原因在于，国内有一句话叫做，南电信北网通。这两家运营商之间互相屏蔽造成无法互通。通过使用高防BGP线路的主机是可以完美的解决掉这类问题的。 优势三：实现单IP的高速访问相比于双线和三线等服务器，BGP线路的主机只需要设置一个IP即可，可以轻松的实现单IP多线路的访问体验效果。这种效果是一般线路主机无法超越的。 联系快快网络客服小黄QQ98717256-------智能云安全管理服务商-----------------快快i9，就是最好i9。 快快i9，才是真正i9！

快快网络厦门BGP怎么样
快快网络新上产品-厦门BGP。目前该bgp是三线bgp包含了电信线路、网通线路、移动线路。网络稳定性高达99.9%是福建省最大的T5级机房。极度适合企业客户、网站类、软件开发类、小游戏、app等业务。目前厦门bgp也承接托管。欢迎实地考察，厦门地区免费专车接送。 厦门BGP具体好在哪里呢？首先厦门bgp实现了真正的三线bgp，包含了电信网通移动。 关于BGP线路服务器的优势主要有以下几点： 优势一：可智能切换至最佳线路，保障网络稳定BGP可以智能的判断服务器端和客户端的状态，并自动选择最快的带宽来去提高连接速度，使访问者能接入到最优质的的线路中进行访问。一旦出现线路故障，例如单一线路故障时，BGP线路可以自动将用户转接到其他正常的线路上去访问。 优势二：解决南北不互通问题，实现跨运营商快速访问国内主机访问速度慢的一个原因在于，国内有一句话叫做，南电信北网通。这两家运营商之间互相屏蔽造成无法互通。通过使用高防BGP线路的主机是可以完美的解决掉这类问题的。 优势三：实现单IP的高速访问相比于双线和三线等服务器，BGP线路的主机只需要设置一个IP即可，可以轻松的实现单IP多线路的访问体验效果。这种效果是一般线路主机无法超越的。 联系快快网络客服小黄QQ98717256-------智能云安全管理服务商-----------------快快i9，就是最好i9。 快快i9，才是真正i9！
