Sorry I didn't try yet your suggested image. Today has been very busy
for me and I had to use the spare time for some webkit/efl tests,
however I want to remark here that the "slowness" I saw in my tests with
the keyboard aren't related to the Illume keyboard slowness in looking
up the dictionary.
This is a bug that is completely illume related and that doesn't affect
my experience in any way (since I'm using a very small dictionary, and
also because that bug doesn't cause to ignore the taps, only it makes
the words-search very slow [i.e.: every tap is taken anyway, also if
takes longer to be analyzed]). As add on, I'm using the same rootfs for
my tests (i.e. the same illume version and configuration).

I neither think that the new kernel is slower in analyzing the
touchscreen events. Simply it uses too strong filters imho.
