Performance issues are fixed recently (at least I hope so), but it
will took some time in order to get fixes in stable. Unfortunately I
don't have any IT9135 BX (ver 2 chip) dual device to test like yours...
Could you install that kernel tree:
http://git.linuxtv.org/cgit.cgi/media_tree.git/log/?h=devel-3.17-rc6
and firmwares from there:
http://palosaari.fi/linux/v4l-dvb/firmware/IT9135/ITE_3.25.0.0/
OK I have
http://git.linuxtv.org/cgit.cgi/media_tree.git/log/?h=devel-3.17-rc6
running now (reporting itself as 3.17-rc5), with the 3.40.1.0 firmware
from your site.
Both tuners work for all stations, except that the first tuning attempt
on each tuner simply doesn't lock. Doesn't seem to matter what I tune to.

I left it trying to tune for minutes, and occasionally it would get a
lock for one sample but then lose it again for the next.
