i developed a tcp-c (http://www.tpc.org/tpcc/) benchmark application to evaluate the performance of different newsql dbms.
except of the results in cockroach everything seems reasonable.
cockroach is the only db which shows a performance improvement (~ 20% faster) when the cluster is secured.
i use the same environment setting (hw and sw) and tried it several times.
are you familiar with this behaviour?
are there some dependencies which are activated when the cluster is secured which could lead to a performance improvement?
i am thankful for every hint.
