Dedicated server is a physical server that you can lease from the hosting provider. This allows you to have full control over the server including the choice of operating system, hardware etc. You DO NOT need a dedicated server if you are just starting out. Once your site is receiving a significant amount of traffic, then you should consider upgrading to a dedicated server. WPBeginner runs on a dedicated server by HostGator. If you do not employ a system administrator or have no experience with servers, then we recommend that you get a managed dedicated server. WordPress hosting providers that offer managed dedicated servers employ full-time system administrators that maintain your servers. Along with doing software updates, they also do server monitoring, offer phone support etc. Most top websites use clusters of dedicated servers.

There probably are, but we highly recommend that you stay away from them. In most cases, free WordPress hosting providers put advertisements on your website. They may even distribute malware to your users. Last but not least, they can shut down your website at anytime without any notification. Avoid anyone who offers to give you free WordPress hosting, specially if you are serious about your site.

It’s quite easy to get overwhelmed with all the information overload. Often users read this guide, and email us asking for personalized recommendation on which WordPress hosting is best for their needs.

针对这个现象,IBM的论文给出了一个合理解释。这是因为当有2块CPU同时对内存进行访问时,内存读写的控制将会变得比较复杂,因为两块CPU可能同时读写同一个地址的数据,需要对内存数据进行一些同步操作,从而导致内存读写性能的损耗。这种损耗即使对于物理机也是存在的,可以看出右图的内存访问性能数据是低于左图的。2块CPU对内存读写性能的损耗影响是非常大的,这个损耗占据的比例远大于虚拟机和docker由于内存访问模型的不同产生的差异,因此在右图中docker与虚拟机的随机内存访问性能上我们看不出明显差异。

As you can see, our test site loaded in just under a second for a server in Dallas, Texas. That’s faster than 94% of all tested sites. Considering the fact that our sample website wasn’t using any caching plugins or speed optimization tips, this result is amazing.

通常一个虚拟主机能够架设上百至千个网站。如果一个虚拟主机的网站数量很多,他就应该拥有更多的CPU、内存和使用服务器阵列,如果从虚拟主机主机分销商reseller处购买虚拟主机的话,虚拟主机主机分销商为了达到最高的盈利,在一个主机上架设了尽可能多的网站,而虚拟主机服务器却没有提示,造成客户的网站在虚拟主机的速度受阻。所以,最好的办法就是找寻一家有信誉的大虚拟主机提供商,他们的每个虚拟主机服务器是有网站承载个数限制的。但这个一般都是不公开的。当然如果对网站有很高的速度和控制要求,最终的解决方案就是购买自己独立的服务器。

Last but not least, we use Bitcatcha service to test server response times across numerous geographical locations including United States, London, Singapore, Sao Paulo, India, Sydney, and Japan. This helps us decide which hosting company is best for which geographical location.

  稍早时间我曾经介绍过“免费中文博客服务评测”,主要介绍了国内外免费博客服务(BSP)。这次我主要介绍基于Wordpress系统的免费博客服务(free wordpress blog hosting)。为什么选择Wordpress系统呢?因为Wordpress是一款著名的开源软件,完全免费,功能非常强大,插件众多,使用简便,可定制性也较强,目前已经在国外成为主流Blog系统。下面是我将介绍一下国内外主要的Wordpress服务提供商。

HostGator is a popular web hosting company that hosts over 8 million domains. WPBeginner website is hosted on HostGator dedicated servers, and we have been using them since 2007 for our various websites.

指计算机硬件系统中用于放置主板及其他主要部件的容器(Mainframe)。通常包括CPU、内存、硬盘、光驱、电源、以及其他输入输出控制器和接口,如 USB 控制器、显卡、网卡、声卡等等。位于主机箱内的通常称为内设,而位于主机箱之外的通常称为外设(如显示器、键盘、鼠标、外接硬盘、外接光驱等)。通常,主机自身(装上软件后)已经是一台能够独立运行的计算机系统,服务器等有专门用途的计算机通常只有主机,没有其他外设。

    不管是哪一种双线,都需要对用户和服务器的IP地址进行解析才能选择线路,所以IP地址解析技术、设备和一个完善庞大的地址库是非常重要的--其原理是用户访问网站时先向DNS服务器查询这个网站的IP地址,而DNS服务器会判断用户是电信上网还是网通上网?是电信上网就返回电信IP地址;是网通上网就返回网通IP地址;这样实现智能判断,智能识别的目的。由于这种解析技术有一定的门槛,所以不是每个运营商都能够实现,而只有采用了智能 DNS 解析的双线主机才可以说的上是真正的双线服务。
    The green line represents page load time and the blue line represents number of users on the site. As you can see, our test site performed really well up to 80 users, after that it started to slow down.
    现在,您已解压了安装文件夹、创建了 MySQL 数据库和用户并自定义了 WordPress 配置文件,那么也就准备好将您的安装文件复制到 Web 服务器文档根目录,以便可以运行安装脚本完成安装。这些文件的位置取决于您是希望 WordPress 博客位于 Web 服务器的实际根目录 (例如,my.public.dns.amazonaws.com) 还是位于根目录下的某个子目录或文件夹 (例如,my.public.dns.amazonaws.com/blog) 中。
