Hi Ralph -

>I don't see why the beta4-to-beta11 step would increase an IOCs boot up
>speed - do your IOCs have NFS access to their boot server?

I use NFS.  Also, see Marty's "Big Database -> Slow Boot" mail in the
April archive.  

>If you use templates, the .db file gets opened once per instantiation 
>(this leads to an overhead of ~1 second per instance!!).

Yes, I need to use more templates.

Here are my statistics:

CPU:      NI-Cpu-030 (16 MB)
OS:       vxWorks 5.2
EPICS:    3.13.0.beta4
Database: 1061 soft and 825 hardware records
          (sums up to 1886 records; 6.1 MB of allocated memory)
Seq:      10 state sets
Load:     ~35% (when idle)

Boot up:  reboot until iocInit  3:10 min
          iocInit               2:50 min
          after iocInit         1:00 min
            (sequences and save/restore monitor sets)
(Note: my iocInit takes long because it has to set up 9 special VXI modules
       involving file IO to load DSPs, etc)

Obviously I have work to do to speed up my boots.  

Ralph, thanks very much for the useful information!
