What is MySQL overloading?


What does it mean to overload MySQL?

A database is used by most dynamic websites to hold dynamic data such as posts, comments, products, accounts, and so on. This information is kept on database servers. The data stored in the database can then be seen and modified through your website's interaction with it.

 To supply and alter the data you submitted through it, the database server must work. Most dynamic websites must conduct numerous queries for each page accessed, so a database server must be quick or your website will be significantly slowed.

ProFreeHost monitors the server load on a regular basis in order to keep the database servers' load low (and the websites that use them fast). An automated system will be activated if it is judged that the database server load is too high, resulting in decreased performance on the websites that use it.

The system will then determine which database server users consume the most database server resources. The system will then suspend the accounts that are putting the database server under the most strain, which will be suspended for 24 hours.

This system keeps the database load minimal, allowing websites that use the database to load quickly.

How could my website cause the database server to become overburdened?

There are a variety of circumstances that could cause your application's database load to be excessive. The following are some of the most typical issues:

  • Your website experienced a big number of hits, which resulted in a large number of database connections being opened and database queries being run.
  • For each request, your website code conducts a large number of database queries.
  • Some of the database queries you run require a significant amount of computing power. Queries that process a large amount of data, have sophisticated subqueries and joins, or do not employ indexes appropriately can put a database under a lot of stress.

What can I do to lighten the burden on my database?

Here are some strategies to assist you reduce database consumption (and make your website load faster) if you utilize existing software and do not create the database queries yourself:

  • Unnecessary plugins and scripts should be removed from your website. The majority of plugins and addons run their own queries, therefore the less software you have installed, the fewer database queries are run.
  • Install caching on your website so that frequently requested data is not retrieved for each request.
  • Here are some techniques for optimizing MySQL queries if you wrote them yourself:
  • Make sure that each request has just one database connection, and that you use it for all queries. It is faster and lighter to reuse a single database connection rather to generating a new database connection for each query.
  • Large database bulk jobs, such as major analytics searches or imports, should be avoided. Database servers for web hosting are designed for frequent, light use, not for huge data analysis.
  • To see if queries are running optimally, use the MySQL EXPLAIN function in phpMyAdmin. If your queries are reading a large number of rows, you can consider adding indexes, rewriting the SQL query, or changing the database schema to make the data retrieval more efficient.

How do I keep my website online if the following suggestions do not work for me?

If your memory use is still too high after following the above guidelines (or if you are having problems implementing the tips on your website), you should consider upgrading to premium hosting.

The database usage restrictions on premium hosting are significantly higher than on cheap hosting, allowing your website to expand. When you add in other premium hosting benefits like free SSL certificates, Cloudflare RailGun, and an award-winning cloud hosting infrastructure, you can be confident that your website will remain fast and stable.
