I can safely say that it's not really an immediately impeding problem with 1 GB of RAM either. I have a bit of experience in the context as I develop and manage a very large Perl software stack that runs on a fleet of servers ranging from itty-bitty to small/medium. Some of it is inefficient CGI, some of it is FastCGI, some of it is resident in the background and some of it fires up on intervals. All of it is heavily trafficated. But, certainly, I'll concede that if the platform is completely CGI-based and for some reason is written such that there's a minimum footprint of 50-100 MB for any single invocation, then servers will be needing a bit of memory in lieu of a software rethink.
