Long startup time with Google Drive

It takes about 2 min to start Cryptomator and until the files are revealed. During that time I see a high disk load in the task manager for Google Drive.
Are 2 min normal for a larger drive size? Or is there anything I can do to speedup things?

I am using the latest Cryptomator version 1.6.3 on Win10 together with Google drive. The size of the encrypted volume is about 100GB with 100k files. The local cache is on a HDD with a speed of ~130 MB/s.
