Hello everyone,

I've been eyeing C5 for a while now, and was also considering drupal until I started getting annoyed with the way the forum is integrated (rather not integrated as nicely).

My current website is a non-profit site for teachers who are overseas teaching EFL/ESL, and it mostly provides lesson-planning, and general advice/suggestions.

System it is on runs Debian Lenny 64bit, MySQL, Apache2. (Forum system: SimpleMachines 2 beta)

I'm looking to migrate over to Gentoo (64bit as well), MySQL, and NGINX (CMS system: C5). Apache has been a bit of a memory hog with my site having about 500-900 simultaneous connections at the peek times of the day. I'm not too sure if using a different database engine would make much of a difference, but I'm looking at tweaking the config I have for my setup of MySQL.

In any case, my question is a two parter:

1. Should I be worried about C5's performance for a site that has a growing number of concurrent connections. Should I just stick with a forum software, and try to build around it (so to speak) for what I need? That being said, I really love the way C5 integrates with its forum system. I understand the other issues involved such as server resources, and possibly separating database and web server to different servers. However, comparatively, I'm concerned about C5's performance relative to other CMS like drupal or even a forum software like phpBB or SMF.

2. I'm willing to pay for support, but was wondering if it would be possible to find someone here with enough time and knowledge to help me migrate user accounts (details,passwords, status...), and posts (including attachments that are currently stored under one global directory, to more specific /attachments/$username directories depending on who posted the content).

Any help or guidance would be very much appreciated.
