Yes, it took me some time to optimize loading of various components.

First, do profiling and find the loading bottlenecks.

Reading from a large file could be a bottleneck, but one
can mmap a file and work with it faster.

Sometimes, going to native mechanism instead of a QThread
was also working a bit faster.

If you are doing QML - search emails on the list
reporting various issues with QML-related loading and slow paths.

Take care,
Robert
