performance differences between limited and full personalization
Dear friends,
I have a question about possible performance differences between limited and full personalization in mailman 2.1.9. That is, I set up full personalization for two lists that I have (they are more like for sending newsletters than for discussion). Anyway, I wonder whether I would have any gain in terms of performance if I switched from full to limited personalization. I read the description but it does not say anything about this issue. There's only comparison between personalization as such and no personalization at all.
In other words, do I gain anything from changing from full to limited personalization? I like when people recieving our newsletters do not have to guess the email they were subscribed with but if it should help, I would switch from full to limited and place their emails in the email footer.
Warm regards,
-- Zbigniew Szalbot

With respect to performance, there is no difference between personalize Yes and Full. In either case, each subscriber receives an individualized message (whether or not the messages are in fact different). The performance hit is in sending a separate message to each recipient via a separate SMTP transaction. The actual content of the message and the To: header doesn't matter.

Not really. Either way, the system has to create individual copies of the messages to be sent, and that's the biggest performance hit.

Full personalization will change the way the headers look. Users will no longer see that the post is addressed to the list, with them getting a copy. They will now see that messages appear to be directly addressed to them by the sender, without any mention of the list.
One of these behaviours may be more desirable for your users, who may be confused by the other type of behaviour. It's up to you to decide which makes more sense.
