The ease to deploy across my cloud VMs as well in-house servers. I have tested it from various clients with different needs such as high traffic usage, speed tests etc. It always performs very fast both when deployed from an external provider (AWS/Azure) and also internally using KVM virtualisation software like libvirt. Sometimes you can get a bit confused by some features that are not so obvious at first sight but if anything is broken then reporting would be super helpful since the support team is amazing! My current use case has been speed improvement. For me there's nothing majorly wrong, just try it out and see how your users react :) I love how easy it is to use and configure. If you are using cloud hosting, then there is nothing that i dislike about this software. It's one of the best products available in the market. The only thing which could be improved is the UI of the dashboard. Even though it has some minor issues, but those can be easily sorted out with few clicks. We have used varnish to cache our websites. This way we have reduced the load time of our website by almost 70%.
