Maybe you could give it a try by reducing the "Number of key Transformation rounds" in your database.
You find this setting at:
I hope this helps.

Thanks! Reducing the number of transformation rounds can significantly reduce the time to load the database (to less than a second). However, it also compromises security since it enables brute force attacks. Longer passwords do too, but there's a trade-off and 10M rounds is a sweet spot for me.
My real question is how Keepass2Android can be an order of magnitude faster on the same hardware. My guess is that there is some inefficient code in WinPass's implementation, and I hope someone takes the effort to find out. WinPass seems to be the best KeePass tool for Windows Phone, but this slowness may scare users. I sure don't open WinPass unless I absolutely have to.
I have got a moderately sized password database with around 200 entries. For security, it uses 10 million key transformation rounds. Keepass2Android can open this database in 15 seconds on a Motorola Moto E 2014 (Qualcomm Snapdragon 200, 1.2 GHz dual-core Cortex A7). Winpass on a Lumia 640 (Qualcomm Snapdragon 400, 1.2 GHz quad-core ARM Cortex A7) takes many minutes to open this same database, making Winpass inpractical. I understand that opening the database could be single threaded and that the Lumia could be as slow as the Moto E, but I don't understand the order of magnitude difference. Is this expected behavior?
