Limitations on Shared Web Hosting By Different Providers

Spread the love

The shared hosting comes with limitation in terms of resource utilization. The hardware resources of the shared account are limited so one user can not utilize more resources than he is allowed. This will make the server stable and it will not be slow for others users. Different hosts use different limits. Few of them list their limitations which is good thing as a normal user doesn’t know what is buying. We have listed the limitations placed by few of the popular providers.

Blue Host

  • We only allow 50,000 inodes per cPanel account.
  • With the upgrade to a Pro, Woo Pro, or WP Pro account, the inode limit is increased to 300,000.

All websites hosted on Bluehost Brasil‘s Shared Web Hosting servers are actively monitored, to ensure that they do not impact the performance of other websites hosted on the same server.

Some of the parameters that websites are monitored are mentioned however no exact limitations have been given.

  • Number of concurrent/simultaneous connections a website can make to the server,
  • CPU utilization in terms of a percentage of what is set aside for websites hosted on the server,
  • Memory utilization in terms of a percentage of what is set aside for websites hosted on the server,
  • Number of concurrent/simultaneous processes a user can run on the server,
  • Number of concurrent/simultaneous Database connections a website can make,
  • Number of queries that can be run on a Database in an hour’s span.

Hard Inode Limitations

  • Starter Hosting – 250,000
  • Plus Hosting – 250,000
  • Turbo Hosting – 500,000
  • Business Hosting – 500,000

Hard CPU Limitations

NameHero recognizes that CPU usage isn’t constant. There may be short bursts of activity that require extensive processing on your site – and that’s fine as long as it doesn’t last too long. To this end, an account can only use 25% of the CPU for less than 90 seconds at a time.

Activity Restrictions

In addition to the CPU usage limit above, there are certain limits with regard to CPU consuming activities that are not allowed. For example, SQL queries are extremely CPU intensive, often using up the entire amount available until the query is completed. NameHero doesn’t allow any MySQL query to run for longer than 15 seconds. We also don’t allow programs that run as spiders or web crawlers.

Another activity of interest is running the server for purposes beyond that of web hosting. For example, you can’t create a gaming server such as Minecraft or COD, since these will place unacceptable loads not just on the CPU, but on bandwidth as well.

Host Gator

  • It is unlikely that you hit the 25% CPU usage for 90 seconds at a time, unless your site is script intensive and requires more processing.
  • There is a limit of 25 simultaneous process per cPanel.
  • There is a soft limit of 100,000 files per cPanel; however, accounts that exceed over 250,000 files will be in direct violation of our Terms of Service and will be susceptible to being suspended. 
  • HostGator allows a maximum of 25 simultaneous MySQL connections per cPanel on shared servers. This limit can be raised for VPS and dedicated servers.
  • The 25 simultaneous database connections should be sufficient. Most database connections open and close within a fraction of a second. A forum with 500 active members will rarely hit this 25 simultaneous connections.
  • The SQL server will timeout after 60 seconds of inactivity for Linux hosting (shared and reseller). On Windows shared hosting, the MySQL Server will timeout after 30 seconds of inactivity. VPS and dedicated servers can have different limits.
