Hostgator对系统资源使用的限制

510742

为了服务器的正常运行，保证不会由于一个账户过多占用系统资源进而影响到其他用户的使用，Hostgator主机会对每个账户进行系统资源使用的限制，主要表现在：不得占用系统资源超过25%达90秒以上。为此，Hostgator还给用户一些建议：

User may not:
1) Use 25% or more of system resources for longer then 90 seconds. There are numerous activities that could cause such problems; these include: CGI scripts, FTP, PHP, HTTP, etc.
2) Run stand-alone, unattended server-side processes at any point in time on the server. This includes any and all daemons, such as IRCD.
3) Run any type of web spider or indexer (including Google Cash / AdSpy) on shared servers.
4) Run any software that interfaces with an IRC (Internet Relay Chat) network.
5) Run any bit torrent application, tracker, or client. You may link to legal torrents off-site, but may not host or store them on our shared servers.
6) Participate in any file-sharing/peer-to-peer activities
7) Run any gaming servers such as counter-strike, half-life, battlefield1942, etc
8) Run cron entries with intervals of less than 15 minutes.

Users are strongly recommended to:
9) When using PHP include functions for including a local file, include the local file rather than the URL. Instead of include("http://yourdomain.com/include.php") use include("include.php")
10) To help reduce usage, do not force html to handle server-side code (like php and shtml).
11) Only use https protocol when necessary; encrypting and decrypting communications is noticeably more CPU-intensive than unencrypted communications.

总的来说，尽量减少网站对系统资源的使用就是了。
