    We are considering to change from Plesk to cPanel. Lets say that we would like to have server with 1500 accounts in it. I hope you can help me with answering couple of my questions.

    What kind of memory requirements would you think cPanel server has with 1500 accounts? Is there any issues with cPanel when hosting many many accounts?

    In Plesk there is file descriptors limit so we need to recompile Apache, PHP and IMAP to host more than 900 domains. Is there same kind of issues with cPanel (in packages cPanel uses by default)? Also AwStats in Plesk takes ages to complete with many accounts. In Plesk Webalizer is about ten times faster and won't take all the server resources. Is there same resource problems with AwStats in cPanel? By default Plesk runs PHP from mod_php which makes user permission problems and most of the methods solving the user permission problem (e.g. run by FCGI) makes memory usage problems. Is there same kind of problems in cPanel?

    Thank you very much in advance!

    Best regards

    It's more or less impossible to say how much memory you need with 1500 accounts. It all depends on what kind of sites they're using and how you've set up apache/php and what else you're offering.

    Lets just say that cPanel holds most options open. You're able to use mod_php or fcgi for faster execution of PHP or you could go with the safer option and use suPHP. You can always modify it later by running easyapache again or changing settings in the conf files.

    We've got a server with almost 2000 virtual hosts and it's running smoothly with 16GB RAM and using suPHP. We're leaning more and more towards the FCGID way nowadays though seeing the performance increases in applications like Magento.

    Good luck with your account transfers, I don't envy you ;)
