Excessive sales of foreign virtual host space

For some reasons, I bought some foreign virtual host very early, I have been in the last two years to renew the DreamHost of the virtual host, now I regret to find that I this well-known virtual host service provider's endurance is nearing the limit.

I think the reason for DreamHost's problems is, in the final analysis, a dreamhost, overly-selling (overselling) strategy. Buy a DreamHost virtual host, you can bind an unlimited number of domain names, with 500GB space, monthly traffic 5000GB, so exaggerated configuration really as long as 9.95 dollars, we really can use so much resources?

Give me a practical example, my moonlight blog capacity of hundreds of trillion, the monthly flow of about 450G, I can no longer use the virtual host, I almost always use a stand-alone server, because only a stand-alone server to provide such traffic and CPU support. The same server, only one person to use and have hundreds of people use, the two are completely different, the virtual host can provide a very limited amount of resources, and the dreamhost of such a permanent virtual host is just cheating those network beginners, the virtual host can not provide such a large space and traffic. The reality is that unless your site uses static HTML files, you're already being asked to "upgrade" them before you reach their traffic limit of 1%.

Now, I've received dreamhost emails saying that in the last nine days, my users have spent twice times more CPU time than the average user on this host, asking me to pay more to buy CPU usage and upgrade to DREAMHOSTPS.

In fact, I just built a few WordPress blog system and a discuz forum, in order to reduce CPU load and MySQL usage, I also deliberately used in WordPress static Plug-ins, most of the files are static, even so, in the flow of large, I still found that the site often 500 errors, unable to connect to the MySQL server is a commonplace, I believe that the WordPress and Discuz system itself should not have any problems, and I also did a lot of optimization work, CPU usage should not be very high, But why do we get the result?

At present, I dreamhost on the total flow of all systems are usually not large, the recent period of time to achieve 800M per day traffic, the total use of less than 1G of space, from their configuration requirements are far away from the use of the CPU has exceeded their permission, I don't really know how the other users on this host are using DreamHost, I think, unless I use static HTML to do the site, otherwise it will not meet their demanding requirements.

I do not know how other people are using the virtual host, but I think I have a dynamic language and database optimization has done a lot of work, how others use DreamHost? Other users are all the site traffic is very small, or all static pages, also do not care about the frequent downtime, do not care about the speed, I am really confused.

I'm fed up with DreamHost, and I'm not going to pay for their overselling, I'm starting to look for the next foreign virtual host, and now I'd rather choose a host that only supports one domain name, monthly limit traffic below 100GB, Also will not choose the kind of binding infinite domain name, claiming to provide more than 1000GB per month of traffic service providers, otherwise, it may be another nightmare.

Finally, after I use SSH login, I use the following statement to query the number of users of this server that I use DreamHost, resulting in a total of 380 shell users and 1069 FTP users.
