Sean, That is correct, IXFR is not supported so pdns falls back to using AXFR for the transfer. I had posted a patch to at least allow for the DB update process to be optimized a few years ago. This kept the DB backend from being overrun by the AXFR updates. It sounds like your best bet is to script/cron the update to occur periodically instead of every second to manage the I/O. Good luck.
