So, we have a UI choice in lists.launchpad.net which is to show the list of messages with newest first.
This is nice to use, but performs poorly. We have a medium/long term fix of moving to an SOA, but right now this causes massive latency - its a quadratic algorithm as each message received rewrites the entire archive for that list for the current time period. If we move to an append mode - oldest first - then AIUI only the most recent batch is rewritten, which is bounded by count-per-batch rather than count-per-month (which is the one that currently crucifies us). I propose that the UI impact of messages appearing very slowly is worse than the UI impact of messages being in oldest-first order.
