Figure 6, Figure 7, and Figure 8 show the results of file create, stat, and remove operations,
respectively. As the HPC compute cluster has 64 compute nodes, in the graphs below, each client
executed a maximum of one thread for client counts up to 64. For client counts of 128, 256, and 512,
each client executed 2, 3, or 4 simultaneous operations.
From the three figures, both NSS5-HA and NSS4.5-HA have very similar performance behaviors, as the
two lines for NSS5-HA and NSS4.5-HA in each figure are almost identical; it indicates that the changes
we have with NSS5-HA do not have obvious impact on the performance of metadata operations.
