As you'r aware, the Windows port of Hydranode is the one needing most of the work and testing right now. So what's going on right now is long-time testing of Hydranode and it's performance on Windows platform, trying to iron out the remaining bugs and improve the performance where needed.
There are some things that seem to block the main thread at times, for example MetaDb saving can take up to 30 seconds on slow hardware, so optimizations need to be made there. Other thing is temp file allocation, which needs to be moved to WorkThread, since on Windows, allocating the new file takes time (different from Linux, where it's almost instant). This and other Windows-port-related things are the current active topics of development.
