On Ubuntu 14.04 with nvidia 337 drivers (not sure if that's relevant) compiz doesn't take up so much memory.

Title:
  Opening the dash causes memory usage to climb dramatically, and never
  comes back down

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  This may not be a bug at all, but thought I'd report it anyway.

  I am NOT reporting a memory leak - at least, I don't think so.  I am
  simply reporting this:

  When I start a desktop session, Compiz uses 85M of memory.  It stays
  there as long as I *do not open the Dash*.

  Once I open the Dash - simply pushing the Ubuntu button, and then
  closing immediately - the memory usage climbs to ~120-150.

  If I go through every page in the Dash and open every sub-page and see
  every icon available, the memory usage clibms to ~185M.

  Re-visiting the Dash, no matter how often, doesn't cause a further
  increase, but I'm not certain the Dash should use ~100M of RAM all by
  itself.  I'm not sure how much it *should* use, but it just seems a
  bit excessive.
