How to speed up MySQL server for express loading of sites
Many websites run applications that are database driven. Fetching the data from relevant databases and delivering the contents dynamically to a web page, is what most of these applications do.
As the data content or traffic increases, we’ve seen that these applications tend to get slow over time. In our role as Outsourced Tech Support for web hosting companies, we speed up MySQL server for our customers who are web hosts.
Today we’ll see what are the different scenarios that slow down the MySQL server and how we get over them.

What causes MySQL server to slow down
A server is only as good as its components and configuration. MySQL performance slows down due to memory, CPU or I/O overhead, due to any of these issues:
1. Poor hard disk performance
A slow hard disk or a degraded RAID array can lead to higher disk access time, and slow down the database operations. Bad sectors in the hard disk or too many failures can lead to poor performance.
2. Inadequate memory
The RAM size required by MySQL to perform its transactions would vary with the type of queries and the database size. If the RAM size is not enough, this can slow down MySQL by incurring too much wait to process queries.
3. Type of transactions
Write operations are usually slower than read operations. As a result, the type of database queries and the size of data involved, makes a huge impact on the performance and speed of MySQL transactions.
4. Improper MySQL configuration
Every MySQL server differ from each other, based on the type of transactions and applications supported by it. Custom configuration settings are therefore required to fine-tune and speed up each MySQL server.
5. Unoptimized DB queries
An online business showcases its identity via its website. Many websites use custom code in their web applications. If these queries are not optimized and contains complex joins, it can cause MySQL to slow down.
Now, we’ll see how our expert technicians speed up MySQL server for web hosts using various compile time and run time tweaks.
How we speed up MySQL server
Our expertise handling different web hosts ranging from web site owners to cloud hosting providers has bestowed upon us, a clear idea regarding the various settings required for each server type.
At Bobcares, our dedicated server specialists assists customers to choose the server specifications based on their hosting requirements, which helps them deliver the best performance to their customers.
But just adding memory or CPU is not sufficient to ensure a high performing MySQL server. We perform the following optimization methods to further speed up MySQL.
1. Compile-time options to speed up MySQL
For servers that require maximum performance for MySQL, we compile the server statically, without enabling the debugging feature, to avoid overhead and increase speed.
By enabling only the required character sets for MySQL, we bring in further improvement in speed. Choosing between MyISAM and InnoDB tables is another decision we make based on the type of connections required.
