We do about 10K updates an hour on our master server. The only real issue
I've seen is that the journal files can get quite large. Ours were growing
over a gig in under a month. This became an issue because bind opens the
journal and seeks to the end whenever it needs to log a change. Once the
journal grew large enough we couldn't process updates fast enough.
Fortunately Bind added support for journal compression a few versions ago
(Added in 9.3.0, stable in 9.3.1, IIRC), and that solved that problem
nicely.
