What’s important and what I tried to convey in my previous messages is that users/companies with large needs can use XWiki and not be blocked. If we do one DB query per user for example they’ll never be able to succeed in sending 100K mails fast. OTOH they can act at the mail server level by having a farm of mail servers. So we need to scale and be fast up to the point when we’re ready to send the mails. If the mail preparation is too slow we may even need to change our architecture/design too in order to spread the preparation of emails on various XWiki instances or delegate that to some external processes (by putting the requests on a queue, to be handled by those external processes). Or at least have a design that allows companies with large needs to replace our implementation which one that does this. Note that this since XWiki is component-based it’s probably already possible to do that but we need to make it as easy as possible and document it. Thanks -Vincent [snip]
