I did the test and lookign at this function
def getEntityFromTypeArray(self, typeArray):
"""
get entitys from an array of type
"""
_outObj=[]
_dbEntRow=self.getMultiFilteredEntity(entityTypeArray=typeArray)
-->> here we have 31 Mb and all the entity are in the _dbEntRow
for _row in _dbEntRow:
_style=_row[4]
_dumpObj=pickle.loads(str(_row[3]))
_objEnt=PyCadEnt(_row[2],_dumpObj,_style,_row[1])
_objEnt.state=_row[5]
_objEnt.index=_row[6]
_objEnt.visible=_row[7]
_objEnt.updateBBox()
_outObj.append(_objEnt)
return _outObj
--> here we have 400 Mb approximatively

Matteo
