But I'd have to login to each box, spend a good amount of time on the server, understand the business requirements, and then deploy Varnish. It was hugely time consuming but I loved doing this. It was less about bean-counting but rather more about helping. Also progress seemed slow at first because I would gain one user every 2 or 3 days. But word-of-mouth buzz from people I've helped was the thing that moved the chains for me.
The cPanel WHM platform has been moving quite fast over last few years. And so did several things under the hood. I also wanted to build new features that just couldn't be done on cPanel. I felt the project had potential to expand and reach a much larger subset. And that's when I built Cachoid [2].
