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> |
