Throttling can be used to actively limit a user’s upload and download rates on programs such as video streaming,
Website throttling is the intentional slowing of website. It is a reactive measure employed in communication networks in an apparent attempt to regulate network traffic and
minimize website congestion. Website throttling can occur at different locations on the network.
On a broader level, the internet service provider may use bandwidth throttling to help reduce a user’s usage of bandwidth that is supplied to the local network.
Bandwidth throttling is also often used in Internet applications, in order to spread a load over a wider network to reduce local network congestion, or over a number of servers
to avoid overloading individual ones, and so reduce their risk of crashing, and gain additional revenue by compelling users on to more expensive pricing schemes where
bandwidth is not throttled.
Usually website throttling occurs due to the following reasons:
1. Poorly coded PHP scripts such as multiple nested loops, or infinite loops.
2. Themes, Addons, or Plugins (if you just added a new component to your script, you may want to remove it to see if that new component caused your site to suddenly perform slowly)
3. Queries that take too long to execute due to heavy aggregation commands like SUM, COUNT over very large datasets without proper indexing.
4. Queries that are doing complex unoptimized nested Joins.
5. Queries that execute large batch commands like INSERTS, UPDATES, OR DELETES – these types of sql calls are 10 times more expensive and resource intensive than the SELECT query command.
6. Too many simultaneous connections like Downloads, FTP, IMAP, or PHP
Here are some steps that you can take to improve your site’s performance.
1.Try deactivating all plugins and check to see if this resolves the problem. If it does, activate the plugins one by one until you find the problematic plugin(s).
2.Try using “WP Super Cache” plug-in and don’t forget to delete unnecessary plug-ins.
3.Try changing themes or using the default one and see if there is a speed increase.
4.If you are loading pretty large images, you can try optimizing those.
5. Optimize your database through phpmyadmin.
