Metadata performance with MDtest using empty files
The system gets very good results with Stat and Read operations reaching their peak value at 64 threads with
~486K op/s and at 1024 threads with ~186K op/s respectively. Removal and create operations attained the
maximum value at 256 threads with ~116K op/s and ~105K op/s respectively. Once they reach their peak
value, for stat and read operations the performance does not drop below 440K op/s for Stats and 182K op/s
for Reads. The create operations show some variability after it reaches a plateau. However, the file removal
operations remain more stable and does not decrease below 100K op/s.
