I have an application, SIDSuite, that I've been running on my hardware
here for about 18 months continuously, with reasonable performance
(the UI isn't totally-snappy, but acceptable). Some time recently,
with an upgrade of Gnu Radio, the performance became utterly
unacceptable--the UI became unusable, and updates to the FFT and
Waterfall sinks became very "chunky". I haven't changed the
app in months and months.
So, I started taking my Gnu Radio back further and further in time,
until I was back to "normal". I had to regress my GIT tree back to:
commit 2ed887b69a3b15840830998c4e6157176d427f60

In order to get decent performance again.
I have no idea what's causing the performance melt-down, but regressing
back to that commit fixes it, again with no changes to the
application in question.
I will try creeping forward from this commit to see if I can narrow it
down. Blah.
