网速慢的原因及解决办法

网速慢的原因及解决办法 一、网络自身问题 您想要连接的目标网站所在的服务器带宽不足或负载过大。处理办法很简单，请换个时间段再上或者换个目标网站。 二、网线问题导致网速变慢 三、网络中存在回路导致网速变慢 四、网络设备硬件故障引起的广播风暴而导致网速变慢 五、网络中某个端口形成了瓶颈导致网速变慢 实际上，路由器广域网端口和局域网端口、交换机端口、集线器端口和服务器网卡等都可能成为网络瓶颈。当网速变慢时，我们可在网络使用高峰时段，利用网管软件查看路由器、交换机、服务器端口的数据流量;也可用Netstat命令统计各个端口的数据流量。据此确认网络数据流通瓶颈的位置，设法增加其带宽。具体方法很多，如更换服务器网卡为100M或1000M、安装多个网卡、划分多个VLAN、改变路由器配置来增加带宽等，都可以有效地缓解网络瓶颈，可以最大限度地提高数据传输速度。 六、蠕虫病毒的影响导致网速变慢 七、防火墙的过多使用 。防火墙的过多使用也可导致网速变慢，处理办法不必多说，卸载下不必要的防火墙只保留一个功能强大的足以。 八、系统资源不足 您可能加载了太多的运用程序在后台运行，请合理的加载软件或删除1.6.1 sweeping, washing preparations (1) after the pressure test is completed, before purging: purging of piping system; (2) should be made available in accordance with the owner's sweeping plan to draw sweeping system detail; (3) prepare the provisional purging, flushing tube, temporary filter, bypass or blind plate, and mark on the single line diagram; (4) ready to purge and test tools, such as: target, transparent glass.

By-pass, wash downstream parts of the pipeline. (5) take exit of the flushing line with glasses of water, check whether the water color and transparency consistent with the entrance is qualified. After passing the line, water should be drained; (6) if the water pipes, design or party files require drying, you should dry it with compressed air. 1.6.3 air purge (1) air purge media should be no pollution and air under pressure, the pressure of sweeping shall not exceed the working pressure; (2) the competent first purge, then pipe purge; (3) devices are unlikely to participate in the purge, equipment and pipelines should be separated, and to protect the device, preventing rust, and pollutants to the top. (4) the purge should be clearly identified to prevent hurt; (5) by the owner, supervisor, principal of check purge outlet, no rust, debris, and other, confirmed the pipeline purging qualified. 1.6.4 steam purging (1) before steam blowing pressure test and insulation should be completed; 4.删除从没使用过的文件 第五:重新安装已损坏的程序 第六:使用优化软件对系统内存进行优化 第七:重新启动电脑。如果只是关闭程序，而没有重启电脑，程序可能没有将内存完全释放。 第八:减少自动运行的程序。 第九:查杀病毒 以上是如何提高电脑的运行速度，要提高上网的速度及效率，在保证做到上面所说，还要做到下面几点: 1、选择合适的上网时段，避开上网高峰; 2、若只是浏览网页的信息，把一些动态网页效果、音频、视频、图片、动画等效果，通过设置浏览器的属性，把它们关掉，这样可以大大提高上网浏览信息的速度。 3、不要开启多个网页窗口，做完一件事后，再做另一件事，这样可以节省电脑资源，提高效率。 4、在浏览网页的时候，为提高浏览速度，不要同时下载其它软件和文件，应在空闲时间下载所需要的软件或文件。 原因分析二 1.6.1 sweeping, washing preparations (1) after the pressure test is completed, before purging: purging of piping system; (2) should be made available in accordance with the owner's sweeping plan to draw sweeping system detail; (3) prepare the provisional purging, flushing tube, temporary filter, bypass or blind plate, and mark on the single line diagram; (4) ready to purge and test tools, such as: target, transparent glass.
