This long startup is also a bit unusual. Sure, it needs to allocates some 
memory, and this informations needs to be written to syslog, but several 
minutes is too slow. Do you read some database content in memory on startup, 
like a huge location table, or a big carrierroute route tree with several 
hundreds of MB?

So in which processes is the rest of the CPU time spend?
