where to and how to specify big_writes option inside python file?

[Gorparth]

I've implemented GDriveFS and OnedriveFS, I've inherited fuse.Fuse in my defined class, and instance is created like this if name == 'main': authed_usr = GDrive() gdrivefs = GoogleDriveFS(version = '%prog ' + '0.0.1', usage = 'GoogleDrive Filesystem ' + fuse.Fuse.fusage, dash_s_do = 'setsingle') gdrivefs.parse(errex = 1) gdrivefs.flags = 0 gdrivefs.main()

In this what should I add to make read/write speed faster, (big_writes,max_readahed,max_write,etc), or how to add these parameters with exact syntax?
