I think the DPM machine (.188) has 6X1600GB SSD. Could you confirm?

Check the network bandwidth. As the results shows DPM client is network bounded, so we would need to revisit this configuration.

Can you upload the test scripts or codes that generate the payload to https://github.com/futurewei-cloud/alcor-int/tree/master/tools? This can be done in a sperate PR.

| On A-E there are 2600 ACA running on each box, ACA code has been revised to cut off the ovsdb and mq operations |

2,600 or 2,000? I thought 2,000 is the stable setup. Need to update the image accordingly.

Can we add one more data point of 256 threads? People will be interested in seeing the limit.

also can we put some resource utilization diagram including CPU, RAM, Disk IO and Network IO in this extreme case? This would help.

Please explain the x-axis, what do those numbers represent? for example, first number is number of threads and the second number is number of successful run out of a total of 10K runs.

Also, as discussed, we need to verify the extreme large value (5,594,098) and rerun the test.

This image is important. Let us work to collect more data based on two dimensions (concurrent thread # and neighbor numbers), fix one and adjust the other.

Same comment as to image other-ov-jc.png.
"Let us work to collect more data based on two dimensions (concurrent thread # and neighbor numbers), fix one and adjust the other."
we can take out the data point for "1t-1w" and explain in the texts.

The column and row of this table is opposite of the next one. Could we make them consistent?
