[OSM-dev] MySQL on dev

As a mapper without a developer account, I'm very dependent on 
having a working tiles at home server.  Currently, the "dev" server 
is used for t at h and I think it would be a good idea to move this 
subproject out to its own server.  I can't blame other projects on 
dev from stealing resources from t at h, because it is actually the 
other way around.

Still, I get a bit curious when I learn from the Munin graphs [1] 
that a MySQL server on "dev" processes 90 "replace" queries per 
*second*.  Obviously, this cannot be the t at h request queue, since 
that receives and dispatches less than one request per second.  
Can somebody with an account on dev explain what this exciting 
massive database update is all about?
