Following yesterdays published VPS performance data and reading some of the feedback relating to testing virtual systems I received, I wanted to revisit Digital Oceans numbers again. For what its worth, I really like these guys, I applaud them for bringing another quality hosting solution to market at is undeniably a fantastic price. I’m committed to hosting my blog on their $5 server so I’ll be watching with a keen eye how the performance trends.
I created two new droplets today, a 512MB / $5 per month and a 2048MB / $20 per month droplet. I re-ran the tests from yesterday to see how these new droplets would perform and see if they could level the field with Linode’s awesome results from yesterday. I haven’t had any feedback suggesting that the testing methods were flawed so for the sake of producing comparative results, I’ve left everything the same.
The test details are below but to save you scrolling through all the data to get to them I’ve put the summary table at the top. I’ll put the 2048 droplet results in a separate post to make reading easier. Hope this is useful.
