Hey Roderick,

Looks like an oversight, can you try applying this patch to see if it fixes the issue: http://ndb1.internet2.edu/~aaron/toolkit_window_size_fix.patch

You can apply it by doing:

patch -p1 -d /opt/perfsonar_ps/toolkit -i /path/to/toolkit_window_size_fix.patch

Cheers,
Aaron

Good day

We are busy migrating our 3.3 nodes to 3.4.

When I configure throughput tests I want to use Autotuning = off and specify the window size (the auto-tuning gives us sub-optimal measurements). So I do this in the GUI and save the tests. When I check the bwctl processes, the -W doesn’t appear. Reloading the scheduled tests page shows autotuning=yes for the previously configured tests.

Please advise if there’s a bug with this mechanism? It works fine in 3.3.2.

Thanks,

Roderick
