I have a Essential VPS Plan on my forum (opened 3 months ago). I have CPanel + LAMP. Standard configuration. No particular VPS optimization, i use simply XCache with some addons (XenCache+ BD Cache). In the previous month my traffic grow and i had some problems, my site become very slow when i have many users online. So i think it's time to upgrade my VPS to a superior plan. I love Servint so i chosed to upgrade to SolidFire Essential. They have a good CPanel to Cpanel migration so i don't think i will have particular problem with that, i have just to wait because they have VPS in other region so i will have new IP etc. But now i don't want to stay with Apache, i want to use Centmin and have a super-optimized VPS. 1) If i trasfer my site under CPanel, can i disinstall the panel without "data/configuration" lost? I have some FTP Accounts, configuration with Mandrill, e-mail accounts etc. 2) Is difficult to use Centmin with very little server administration knowledge? The tech guys of Servint said me that will provide very little support if i don't use CPanel, they will help me only about server problems (I have a "tech guy" on my team, but he doesn't have much time so i have to do various things myself). 3) Except of Centmin and Xencache/BD Cache, there are other software/systems to optmize my board? 4) Do you know someone that can help me to install/configure and optmize my VPS for a growing board with an honest price? Thank you in advance for your replies!
