Perhaps you have linked to a non optimized Qt package? (-O0 in stead of -O2)
Not sure how this could happen.
Did you compile it yourself?

Hasn’t anyone else tried out the WebEngineView in Qt 5.5 QML? I just can’t
explain why it takes minutes to load pages that load instantaneously in Chrome
or Firefox. This is really hurting us, especially the unusable Google Maps…

Subject: [Interest] Extremely sluggish browser performance in Qt 5.5
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,
