QIODevice represents considreable overhead, even with just QBuffer, for parsing simple things. Benchmarking showed it was spending 25% of the parsing time inside one QIODevice function or another. So this commit accomplishes two things: 1) it increases the buffer size from 9 bytes to up to 256, which should reduce the number of calls into the QIODevice 2) if the source data is a QByteArray, then use it directly and bypass the QIODevice, thus increasing performance considerably Change-Id: I56b444f9d6274221a3b7fffd150c531c9d28e54b Reviewed-by: Edward Welbourne <edward.welbourne@qt.io> |

README
This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
