Avg Latency of basicdb is 0

[Muktikanta0123]

While loading and running basic db I am getting an avg. latency is 0µsec for read or updates always.

$ ./bin/go-ycsb load basic -P workloads/workloada
***************** properties *****************

Is it working properly?
if not, how to fix the basic db to work properly?
