Hi Ulrich, thanks for taking a look at this. I really appreciate the feedback.
Yes, I agree that MDB probably uses less I/O but the difference I am seeing is
negligible. Contrast that with the difference in avg-cpu usage specifically by
user stats (and note that my MDB consumer has double the CPU - 8 vCPUs vs 4
vCPUs which makes this discrepancy even more pronounced).
And since I am not processing more requests on MDB than HDB, something else
must going on here.
MDB:
avg-cpu: %user %nice %system %iowait %steal %idle
56.00 3.79 1.48 0.01 0.00 38.73
HDB:
avg-cpu: %user %nice %system %iowait %steal %idle
18.48 1.83 3.16 0.02 0.00 76.51
