Wow much quicker start up now for QT, changing that scan size did wonders!
Yes it did help. The thing that I like the best that has changed was the locking scheme. The GUI is a lot more responsive for most operations, like rescan operations. Which also helps with things like syncing, as the core won't be waiting for the GUI.
On the surface it may see like the gui is less responsive when it comes to syncing, but that is only because the gui will be updated less often, so the time between updates is larger but the jumps in block counts will also be larger.
Anyway thanks for feedback.
