[vtkusers] Performance issue with 8.1.0rc1

[Robert Maynard]

Are you able to record some performance information so we can dig into
the issue?

Can you build with debug symbols, run performance analysis ( sudo perf
record -F 99 -a -g -- sleep 50 ), and than link us to the performance
data ( perf.data )?
