The hardware's fine :) I was worried about RAM and disk config, but
you're ok there. I have 50MB cache for a DIT of 1100+ users, 2GB RAM -
but the system's also running the MTA, IMAP, MySQL with a 12GB MySQL
database, growing fast. 2GB is more than enough at the moment.
My resume - CV - says that I speak a few languages fluently. I
have academic qualifications in all of them. It doesn't mention
"catese" or "dogese". I speak fluent catese and reasonable dogese,
but I've never taken any exams in them, never needed to.
