I've pushed a new version,  look like I added those since my last
"publication".

That seems like a long time;  has Outlook completed sync-ing?  I assume
the CPU pegging is done by ogo-zidestore and not PostgreSQL?

I do see high-cpu utilization when I first start Outlook but it slacks
off once everything is in sync, and fairly quickly if the cache is full.
But even then the server remains responsive;  the ngobjweb module stacks
up the requests and shoves them though ZideStore as fast as it can.
