Hi,

First off, I'm not a DBMS zealot.  :)  If there's hard evidence which 
says the business requirements requires 500K IOPS for an i7-like box 
with a consumer grade SSD, then that's that.

The MySQL numbers I provided was on my i7/SSD rig however it was run:

o In a VirtualBox VM
o With a single processor configured

When I allocated more CPU's to the VM, MySQL dutifully used them.  I 
suspect I could easily see 500K IOPS (if not more) because 1) they're 
all logical (CPU) and 2) of my SSD.  :)

I don't have the background with akonadi and the dependent applications 
to say anything definitive.  I was just trying to contribute from a 
consultant perspective.  Sometimes people forget to ask those questions: 
  do we really need 500,000 IOPS to support our application for a single 
user?

Cheers!
