 (speed of yum discussion exceised).


  Related yum question on (lack of?) speed when large number of
  updates to do.

 After doing a fresh install, the first yum update can 
 take (for me) hours - this is after I have pre populated 
 the local cache (/var/cache/yum) from another just 
 installed/updated machine - so no downloads 
 to do at all.  The number of updates to be done is of course quite 
 large at this point.

 By breaking this update up into a few separate upates

  e.g
  yum update x*;  yum update kern*; yum update g*; yum udpate

  The time taken seems to be very substantially less (human perception
  unfortunatly I have no benchmarks). 

  I wonder if there is some inefficiency with the dependency tree
  when the number of updates is large that is reduced by
  hand breaking the updates into smaller chunks.
