I had been looking to change web hosts for a while, and thought I’d try out one of the hosts that was offering an SSD option.
I’ve also been learning a lot lately about performance, and how that is measured. This was a perfect opportunity to test the effect of an SSD server. Since I was moving my site, and changing nothing else about it, this seemed like a good comparison.
Now, a few caveats:
- This was measured on my site, given my configuration. Take this all with a huge grain of salt.
- I’m running a WordPress site with a caching plugin.
- I used an individual post as my test page, as most of my traffic goes to one post via search, side stepping the home page
- While on my old hosting setup, I ran that post through webpagetest.org
- I copied over my theme, plugins and database to my new host. I imported my database directly in mySQL. I changed nothing about the settings of my site on the new host.
- After updating my domain to point to the new host, and verifying that it was indeed pointing at the new server, I re-ran that page through webpagetest.org.
- For both tests I’m referencing the Speed Index as my metric
- On first load, the SSD servers seems to have made a huge impact. My speed index dropped from 2428 to 1126 (lower is better), for an improvement of 2.15x.
- Repeat view saw less of an improvement, but still a significant one – 1007 to 802, or an improvement of 1.25x.
Is SSD worth it? Yes, definitely.
While there is still a lot of room for improvement on my site, this change alone provided a noticable, significant impact to my site’s performance.
