Yep, I'm aware GPS is the bottleneck here, and the entries I was quoting were 
from tlsyslog.  Our bench test Compact with GPS disabled comes up much faster. 
:)

Yeah, 10 minutes from reboot to UE attach sounds about right.  Good to hear it 
isn't any longer than it used to be.  Still, 'twould be lovely if moving 
forward, Telrad engineering could start working to make settings changes take 
effect immediately upon config commit.

It makes testing or tweaking settings on a Compact excruciatingly disruptive 
and time-consuming, since virtually every setting requires a full reboot in 
order to take effect.  5+ minutes per change is a long time to be down.

When I was wardriving last winter, and with 2616, I was finding that it took 
almost precisely 10 minutes (from the UE's perspective, running continuous 
ping) to fully re-enter the network upon ENB reboot.

I don't think it's much longer, if any, with 6.6 and the change to 4x4.

A large part of the delay is the GPS acquisition. If you log in to an ENB as 
soon as it will let you (not immediately after it starts returning pings), you 
can watch tlsyslog in real-time. GPS is the single biggest delay, after which 
PHY and RAN come up almost immediately.

FWIW
