I have a large number of files (8M+), and its taking an extremely long time to sync with the Windows desktop client - its only sync’d 0.5M files in 4 hours in virtual file mode.
Also, when my PC goes to sleep, the process starts back from the beginning, which means it will probably never finish!
The MacOS desktop client completed the entire sync in a matter of minutes.
I may be wrong, but the Mac VFS had this option “fast sync” that disapeared and got default way to sync VFS now. And this basically sync folders and content when you actually visit it, so it doesnt actually sync everything from start.
And I feel like there is no “Fast sync” on PC yet, it still write every virtuals files on the hard drive during a first sync.
And I have the same “rate” than you on PC, since it take me like 40min to sync ~130.000 files.
