Test Results Overview
Note: Single Tsung pressure measurement official website pure version Mosquitto (single broker), peak connection number is 197626, followed by the addition of another tsung, altogether two machines together pressure.
Number of connections at maximum peak of a single station:
The number of connections at the maximum of two peaks:
