Hi, for whom it may concern i post my results for vector iterating using iterator and index plus insert via push_back.
the test code is at https://github.com/gunrot/qtcontainerbench <https://github.com/gunrot/qtcontainerbench> in branch vector. it runs over N containers where N=min(1,100000/countofelements) on my OS X 10.10.5 xcode 3.6 13 inch retina apple notebook(2013) Commandline was LANG=C ./qtcontainerbench testCase_iterate_vector -csv Time is in ms. stdvector_fwd_it 5 0,13671875 stdvector_fwd_it 10 0,12890625 stdvector_fwd_it 20 0,126953125 stdvector_fwd_it 40 0,099609375 stdvector_fwd_it 50 0,083984375 stdvector_fwd_it 80 0,095703125 stdvector_fwd_it 100 0,0859375 stdvector_fwd_it 1000 0,072265625 stdvector_fwd_it 10000 0,08203125 stdvector_fwd_it 100000 0,076171875 stdvector_fwd_it 1000000 1,078125 QVector_fwd_it 5 0,23046875 QVector_fwd_it 10 0,20703125 QVector_fwd_it 20 0,23828125 QVector_fwd_it 40 0,234375 QVector_fwd_it 50 0,19921875 QVector_fwd_it 80 0,22265625 QVector_fwd_it 100 0,18359375 QVector_fwd_it 1000 0,1640625 QVector_fwd_it 10000 0,17578125 QVector_fwd_it 100000 0,18359375 QVector_fwd_it 1000000 1,65625 stdvector_fwd_idx 5 0,140625 stdvector_fwd_idx 10 0,107421875 stdvector_fwd_idx 20 0,09375 stdvector_fwd_idx 40 0,107421875 stdvector_fwd_idx 50 0,0947265625 stdvector_fwd_idx 80 0,107421875 stdvector_fwd_idx 100 0,1044921875 stdvector_fwd_idx 1000 0,0771484375 stdvector_fwd_idx 10000 0,0830078125 stdvector_fwd_idx 100000 0,080078125 stdvector_fwd_idx 1000000 1,03125 QVector_fwd_idx 5 0,203125 QVector_fwd_idx 10 0,21484375 QVector_fwd_idx 20 0,21484375 QVector_fwd_idx 40 0,189453125 QVector_fwd_idx 50 0,166015625 QVector_fwd_idx 80 0,16796875 QVector_fwd_idx 100 0,15234375 QVector_fwd_idx 1000 0,146484375 QVector_fwd_idx 10000 0,1796875 QVector_fwd_idx 100000 0,14453125 QVector_fwd_idx 1000000 1,75 stdvector_pushback 5 14 stdvector_pushback 10 11,25 stdvector_pushback 20 9,625 stdvector_pushback 40 7,625 stdvector_pushback 50 7 stdvector_pushback 80 6,75 stdvector_pushback 100 6,4375 stdvector_pushback 1000 5,4375 stdvector_pushback 10000 5,4375 stdvector_pushback 100000 5,6875 stdvector_pushback 1000000 55 QVector_pushback 5 14 QVector_pushback 10 14,5 QVector_pushback 20 13,75 QVector_pushback 40 11,625 QVector_pushback 50 10,375 QVector_pushback 80 11,875 QVector_pushback 100 10,125 QVector_pushback 1000 9,875 QVector_pushback 10000 10 QVector_pushback 100000 10,75 QVector_pushback 1000000 97 My conclusion from this is to use std::vector. Only if i really need the implicit sharing property , because i cannot move, i would choose QVector. Regards, Gunnar Roth
