The standard LAMP is the most popular and most used architecture on the web. Content management systems (CMS) like WordPress, Joomla and Drupal are written with LAMP in mind.
If you’re using a popular CMS, then you’re probably using a LAMP on your VPS.
- LAMP is also free
- Uses open-source software
- And works on commodity hardware.
But LAMP default settings are not always best…
Servers running a Linux LAMP Stack need fine-tuning to optimize their performance.
Here are 6 ways to supercharge your LAMP Stack.
1. Use Opcode Cache for PHP
Opcode caching, aka PHP acceleration, caches the results of PHP code compilation. So next time the PHP is called on, it can simply load from a cache, thus speed up processing.
This is probably the easiest way to optimize the performance of any PHP-based application.
2. Disable unwanted Apache modules
Apache is popular because it’s stable, well-supported and open source. The robust web server has many features and modules. Apache comes with many of these modules enabled by default. And each of these consumes CPU and memory.
But why waste a resource if you’re not using that feature?
Remove unwanted modules/features, and reduce unnecessary overhead.
However, keep it in mind that Apache modules can have shared dependencies, and uninstalling those dependencies can have repercussions. There is no default list for “unneeded modules” and your needs may differ from the next person. So you must be careful!
Don’t just follow a random guide on a blog you found on Google, or your server may quit working! This second step requires research.
3. Use Apache mod_deflate HTTP compression
Enable HTML compression using “mod_deflate” to boost page load speed. This Apache module compresses text, HTML, and XML files by around 70% of their actual size.
All modern-day browsers accept compressed content, and it helps you save server bandwidth.
4. Use Apache mod_expires caching
Adding an “expires headers” using “mod_expires” will prevent re-download of non-expired content by site visitors, and load certain data from their local browser cache, thus speeding up load times.
5. Optimizing the php.ini file
A few tweaks to the php.ini file can improve the server performance significantly!
One of the easiest methods to improve PHP performance is to increase the default memory limit specified in your php.ini file.
The parameter “memory_limit” refers to the maximum amount of primary memory (in megabytes) a script is allowed to consume.
Consider enabling HTML compression and output buffering in the php.ini file. Last but not least, disabling “’magic_quotes_” (now deprecated) and “register_globals” may also result in improved performance.
6. Optimize the MySQL database
Optimizing the database is a very effective performance boost that many server admins overlook! You’ll want to analyze the database queries running on your server, and tweak the MySQL performance to custom match the server needs.
Also, don’t forget about your storage type.
MySQL performance is heavily dependent on storage having a very low latency and high durability under high random read and write IOPS. Below are some rules of thumb when it comes to storage.
RAID is better than non-RAID (especially RAID-10)
Below are a few MySQL optimisation tips to help you speed up your LAMP stack’s performance.
Maximizing MySQL Availability with Clustering
And if your MySQL database is super mission-critical, then the ultimate upgrade is to host the database servers and web servers on separate machines.
Segmenting, or clustering, these server roles on different servers is a major boost as you’ll get serious database redundancy.
You can lose one of your MySQL Proxy servers or one or two of your database servers, and still be able to service query loads from your Apache web servers.
Need help optimizing your Linux LAMP stack?
Tuning a VPS or dedicated server for optimal performance is worth the effort – but it’s not always easy to do. And it takes a lot of time and concentration!
So instead of spending your time tweaking the Linux server, spend your valuable time developing your sites. Let the experienced professional techs at EuroVPS speed up your Linux LAMP stack server and you’ll not only get a faster server, but a secure and reliable server.
