Description
Using QNetworkAccessManager to load files is very slow compared to using RFile. Performance of QNetworkAccessManager is important as QtWebKit uses it to load files and hence suffers a substantial loss of performance compared to using native API. Proposal is to benchmark why QNetworkAccessManager is slower than native API and to optimize performance if possible.
Copy/Paste from findings when benchmarking QNetworkAccessManager against RFile
Some tests show that Qt network access manager is consistently ~50-100% slower in performance compared to using Symbian file access performance. Test code is available if it should be needed.
