Comment 32 for bug 790183

> Why threshold is so low?

I wrote an e-mail to the mailing list explaining the situation in detail back in December: http://lists.freedesktop.org/archives/fprint/2012-December/000376.html

> No synchronous transfers are allowed in driver

The fact that you didn't tell this before is a bit surprising given that the code has been available for more than a month now.

Switching to asynchronous transfers is a major change that would require some effort. And let me put it frankly: your reply does not exactly motivate me to do that.
