Here is a listing of the size of all of the .sav files from our IOCs.
corvette> wc */*.sav
     52     110    1388 ioc13bma/auto_positions.sav
   1728    2890   39737 ioc13bma/auto_settings.sav
    130     266    3485 ioc13bmd/auto_positions.sav

      0       0       0 ioc13ge1/auto_positions.sav

    748    1141   16342 ioc13lab2/auto_settings.sav
  18989   33646  441260 total


Each IOC has 2 files:

auto_positions.sav, typically about 150 PVs, 4KB.
auto_settings.sav, typically 3000 PVs, 75KB.

Hope this helps.
