#2933: Speed up ST_GeomFromWKB
--------------------------+-------------------------------------------------
  Reporter:  strk         |       Owner:  pramsey      
      Type:  enhancement  |      Status:  closed       
  Priority:  medium       |   Milestone:  PostGIS 2.1.5
 Component:  postgis      |     Version:  2.1.x        
Resolution:  fixed        |    Keywords:  history

Changes (by strk):

  * keywords:  => history


Comment:

 NOTE: this fix greately affected ST_Simplify (among who knows what else)
 so that simplifying a collection of ~250k components with a low tolerance
 (not much components being removed) now takes 1.3 seconds instead of 13
 seconds.
