web page loads very slowly at the beginning in the case of QWebEngineViews in different processes sharing the same cache path

[gaojinhsu]

For example, application A has a webengineview to load web page, so we start a process a of application A , and then
process a starts a process b of application A . Since they have the same cache path of qwebengineprofile by setting

QWebEngineProfile::defaultProfile()->setCachePath(path);
QWebEngineProfile::defaultProfile()->setPersistentStoragePath(path);
, process b shows a white and blank webengineview in a long time before web page finish loading. Is there a solution to fix this?

Qt version: 5.15.2
Platform: windows

@gaojinhsu Do you get the same result in release mode ?

I don't have any problem loading pages at all. If you have a slow PC and don't want both running at the same time you'll just have to pause the second one until the first one is done.

Or maybe try setting a different cache path for each different URL?

Try pausing the second for a set time , or not starting the second until the first is set and or done.

@ObiWanKennedy yes, I do.

@Lahearle Can you reproduce the issue following my steps?
