@phenomlab The only thing with Dragonfly is that they have the pricing side, which makes me wonder if that could at some point affect the open-source side. But maybe the pricing is just to have the option to have it on the cloud. But usually when there is money involved like that, at some point it usually affects the free side.
With that being said though, since they are both Redis forks, it would be pretty easy and seamless to switch from one to the other if needed. I am also wondering what the impact would be of using either of these with a Wordpress site? According to Dragonfly, it should be able to make Wordpress even faster with the faster performance. All of that will also depend on the server of course too and internet connection and what have you, but maybe use up less resources if the throughput is faster and multi-threaded.
