| * Improve performance of hfw in qgridlayoutengine by adding more caching.Jan-Arve Sæther2010-11-192-0/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code tried to do caching of queries with constraints too, but it's usecase was rather limited. The caching worked for the simple case of effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); // uses cache The problem was that if somebody called this sequence: effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); effectiveSizeHint(Qt::PreferredSize, QSize(-1, -1)); effectiveSizeHint(Qt::PreferredSize, QSize(10, -1)); Each call would disregard the cache because the constraint was different. Now the pattern is used in the qgridlayoutengine itself when we calculate hfw: (yes, height-for-width). First, we ask for the horizontal size hints with no constraints. Then, we'll ask for the vertical size hints with constraints. Since horizontal and vertical ultimately comes from the same function (effectiveSizeHint) it will invalidate the cache each time. The solution is to add another cache for the sizeHints with constraints. The most notable improvement is in the hfw, nested case. Result: RESULT : tst_QGraphicsLinearLayout::heightForWidth():"hfw, nested": 546 msecs per iteration (total: 546, iterations: 1) RESULT : tst_QGraphicsLinearLayout::heightForWidth():"hfw, nested": 0.000029 msecs per iteration (total: 62, iterations: 2097152) Improvement: 18,827,586 times faster (!!)

* Fix performance regression in QUuid::createUuid()Bradley T. Hughes2010-10-054-1/+76
| | | | | | | | | | | | | | | | | | | | | | After commit 4363d4eebce4afd2ce3b3d6da205f8037357099a, createUuid() would create a QFile, open it, read from it, and destroy it. This resulted in a pretty serious performance regression (report says around 2000 times slower, I measured 3600 times slower on my machine). This change creates one QFile per thread (since QFile is not thread safe) and leaves the file open until the thread exits (at which point QThreadStorage deletes the QFile). This approach is around 600 times faster than the current code, which is around 6 times slower than the original. Unfortunately, it is not possible to restore the original performance without reintroducing the problems that the commit mentioned above had fixed. Benchmark is included.

However, it's about 2.5% slower than pure SSE2 code due to complexity. The results on Atom are 30% improvement over current code, 7% over 4-byte loads, 15% over pure unaligned SSE2 and 9% over unaligned SSSE3.

* Add an SSSE3 version that uses palignr to align.Thiago Macieira2010-08-242-1/+112
| | | | | | | | | Instead of using a non-SIMD method for aligning, we instead load more bytes from p1 and use the PALIGNR instruction to realign to what we want. The result is that it's bit slower than the non-SIMD comparison, due to the complexity. For strings over 8 QChars wide, it's only slightly worse than the non-SIMD comparison.
* Add an SSE2 comparison with prologThiago Macieira2010-08-241-0/+38
| | | | | | | The prolog tries to align p1 to a multiple of 16, so as to run aligned loads, which are faster. Unfortunately, my tests so far indicate that the prolog ends up taking longer than the benefit of having aligned loads.

|/ | | | | | | | | | | | | | | | | | | SSSE3 provides two tools to improve the blending speed over SSE2: -palignr -byte permutation The alignement is enforced on src and dst with palignr to always make aligned access. The extraction of the alpha mask is done with a byte permutation in order to save two instructions per cycle. On Atom, this patch gives between 0% (aligned src) to 10% of improvement (unaligned 4 and 12 bytes). On Core 2, this patch gives consistently 8% to 10% of improvement for every miss-alignment.
