In that example parvalue contains 5 double values (list property) for each parameter. Might be a bit confusing. However that PropertyMapStep is slow. When i put some similar data into e.g. MongoDB for example i can query that as pandas dataframe in less than 1s or even half a second. But in janusgraph it could take up to 60s.
I run this with JanusGraph 0.6.1 on an old simulation server (32 CPUs,64GB memory or something like that).
