# We started throughput test with 1 topic and number of topics present in cluster at that time were 1 (excluding already existing topics 1000)
 # We left it to run for about 2 hours (The mean throughput we observed during this period was 54k msgs/sec)
 # After this, we started creating 10,000 topics one by one using a script
 # We noted throughput values after creating 100 topics and after 200,300,400…so on till 10,000 were created
 # After all 10,000 topics were created we left test to run for another 1 hr.

 During the entire duration, we were producing only on a single topic.
