They have a small app they want to add that requires a newer version of Perl than 5.8.0 that comes with CentOS 3. Rather than getting into a non-RPM version of Perl, we were thinking going to CentOS 4 would be easier and cleaner. In your experience, would you say that my "quick & dirty" measurement of CentOS 4 needing 10-25 MB more memory than CentOS 3 (again, for a non-X box with a minimal install) is accurate (at least in approximate terms)? Or is there something I'm not taking into account -- e.g, some of the libraries and/or other "basic server apps" such as apache with PHP or MySQL will make that number much higher? Although this box is doing OK on memory now, I would hate to kill their possible expansion plans just because we did an upgrade and it sucked up way more memory than we though. Again, thanks for all the great things you and the CentOS team are doing! Regards, KC
