Real-world Application Testing with WordPress
We’re excited to introduce the results of our second testing series with Percona – how ScaleArc accelerates WordPress.
As the world’s most popular content management system and blogging tool, WordPress drives the majority of the Internet’s busiest web sites. Scaling the web tier is easy, thanks to Application Delivery Controllers such as F5 and NetScaler. But scaling the database tier is very challenging – especially when third-party software you can’t manipulate is involved.
In our first benchmark tests with Percona, the tester sent incredibly high workloads to ScaleArc, looking to see how the system how the system performed, measuring introduced latency (they couldn’t find any), and benchmarking the advantages of caching (substantial).
In these WordPress tests, Percona took a different tack, looking instead to benchmark ScaleArc performance under a more realistic production load. Again, the ScaleArc software performed very well, introducing no measurable overhead and providing substantial acceleration with caching enabled.
The test load maxed out the web server capacity. Under this load, the ScaleArc software provided a 3.5x performance increase with caching. If we could have added more web servers, you would see that performance multiple increase far more, because the ScaleArc software wasn’t close to maxed out. For example, we did our own WordPress testing, in which we simulated 100 web servers, and saw a 20x performance increase.
If you’re struggling to keep pace with the popularity of your website, congratulations! And see how ScaleArc can help you solve WordPress performance problems.
