[Interest] Extremely sluggish browser performance in Qt 5.5

[John C. Turnbull]

I am just trying out the "nano browser" in Qt 5.5 on Windows 7 64-bit and
find it almost unusable.

 

Loading *any* website is slow but it is particularly noticeable with Google
Maps.  It can take more than a minute to render the initial map and then
zooming in first shows just a scaled and pixelated version of the map and
then it can several minutes for the details to be rendered properly.  Also,
switching from map to Earth/Satellite view seems to take forever too.

 

What could be causing this incredible slowness?  It's not the network itself
as the same sites load instantaneously in other browsers like Chrome and
Firefox on the same machine and there is no proxy involved.

 

Given that the primary use case I had intended for the Qt browser
implementation is Google Maps, this is all very worrying!

 

Thanks,
