As well noticed that a single ps4000 with 20MS and 8 cascade sinks connected fails to e.g. provide 1kHz samp-rate .. actual samp_rate on the sink (samples passed to FESA) slowly drops to less than 900Hz over time.

Volk support needs to be enabled while building gnuradio itself .. not sure if Christoph did so while building gnuradio. Here the expected cmake output:
-- Configuring volk support...
-- Enabling volk support.
-- Override with -DENABLE_VOLK=ON/OFF
-- Override with -DENABLE_INTERNAL_VOLK=ON/OFF
-- ENABLE_GR_LOG set to ON.
-- HAVE_LOG4CPP set to True.
-- LOG4CPP_LIBRARIES set to /usr/lib/liblog4cpp.so.
-- Could NOT find Sphinx (missing: SPHINX_EXECUTABLE)
To be checked if tehre is a possibility to verify if volk support was enabled during runtime. Does gnuradio run fine if libvolk is missing ?

Added "external" tag, since it would be interesting to see if the bug can be reproduced on some non-GSI system.

2MS
--> this smells bad
R.Steinhagen said that IIR theoretically should be faster (was faster during cosylab tests)
volk_config and wisedom file for supermicro can be found here: https://gitlab.com/al.schwinn/DigitizerDU2/tree/master/scripts/nfsinit/optimization
