No, it doesn't depend on an update itself, if you have "reload" type of SMU.
It takes long time because it loads RSP(s) first, and once it completed it 
starts to load linecard(s) which have separate copy of IOS XR running ot them.
It loads all linecards at the same time, so reloading of 9001 or 9010 takes
almost the same time.

But if you have "Hitless" or "Traffic loss" SMU's, it won't reload the box,
it just does processes restart on all cards and may be fast reset some
