Hi,

  As the entries grows in mysql database in linux intel box, the time taken
to search(select statement) for entries increases linearly. But, when the
entries grows in mysql DB, the time taken to update entries is constant. Why
is it constant at update as entries grows ? Updates includes search for
entry first and update the entry next. So the time has to be linear since
search is the part of update.  Can some one help me out why is the update
time constant insted of linear as entries grows? Is mysql doing any
optimization for update operations? Pls help me out.


Thanks in advance,
