To create UserAgentAnalyzer takes rather a long time. Maybe we are able to
find a way to resolve the bottleneck, but my concerns to implement the browser
detection in such a bad way like it was before also still hold.
Also when I see the benchmarks I would consider to just inform about the
bottleneck and keep it that way, or to turn it gatherExtendedInfo() off if
0.011ms are to much.---
