I've installed aMember and I am working on configuring it, however when I attempt to get to /admin to actually do the configuration the script suite hangs.. bad.. The site has zero users (its new) and I am just wanting to get it going, its hosted on Amazon S3 + cloudfront and all that jazz, so no worries on if there is enough resources. I have a WPMU instance running on the same setup and its flawless in terms of speed, cannot complain. It also is under development, so there is no major load against the box. Ideas?
I would not equate Amazon S3 + cloudfront as being an ideal solution for an aMember installation. What is the PHP version / MySQL version of your images you are using on Amazon? (Can you post a PHPInfo screen) Do other aMember front end pages (signup, etc) run fine, just not admin?
