I was looking into it, however I don't find their pricing appealing at all. Our shared hosting nodes are all SSD cached, 12 Core E5 servers. I feel that by getting a 4 core or 8 core license I am just limiting our customers. Then again I can spend that money on upgrading storage on those servers. Apache 2.4 with MPM event, Nginx and/or Varnish in front of it seems plenty fast. Our customers are happy and I feel that they should be able to use all of the server's resources.
So, what do you guys think? Is LiteSpeed worth getting? Or is it just a badge these days meant to be put on your site next to CloudLinux and cPanel in order to attract more customers?
With managed CMS offerings such as those from WPEngine.com I see potential customers caring less about the underlying platforms and more about the end result.
This is just my two cents. What's yours?
