Ok, I know CloudLinux for years, even before cPanel even supported it. Back then it was not very solid, one of the reason I did not liked it, was because the load averages where screwed up and some specific softwares where having problems with it. Now times has passed and more and more companies are using it, cPanel supports it now, even when I still see it can even affect some cPanel processes which is kind of ironic but here comes my question. Reading a bit about CloudLinux is seems you need to recompile Apache. How does CL identify processes from users? As far as I know they are not under user account under some specific Apache compilation unless you go with suPHP. Also, my biggest concern is. If I get it right, Cloud Linux does this LVE only on web server processes? How about email, mysql, etc? Does it work for all processes from a single account or just web processes? I mean, if it only handles the isolation for web processes then its useless as far as I can see, because some users cause heavy load with email, other with databases, and others with cron scripts. If the answer, is yes, it will work for all processes for a specific account, how will identify them? There is also one thing that I consider a complete killer to not use CloudLinux. Correct me if im correct. It will slow some users websites, is this true? Why not show an error directly when he consumes his resources? This is something not acceptable in my case. I cannot possible have clients complaining the hosting sucks because their website is slow. I don´t see how this can be any good. Customers would never know its done by Cloud Linux on purpose and this would give the company and even cPanel a bad rep in the future like "I look hosting without cPanel that slows websites down". An error is ok, but dropping performance on websites is not. Someone that hires a hosting does it because he wants speed, otherwise he can just host at home.
