 > libglib-2.0.so.0
 > -librt.so.1
 > -libdl.so.2
 > libgcc_s.so.1
 > libpthread.so.0
 > libc.so.6

So what is E.G. the time differences when running

time gst-launch-1.0 fakesrc num-buffers=1 ! fakesink

on a "normal" machine with/without these patches?

(Notice that gstreamer searches plugins and creates cache file first
time it is run).
