+
+As you may have been noticed, average time to send msg is `4.427μs` which is roughly rounded to `4` microseconds 
+within 10 000 have been sent 3 times in a row.
+
 PS U'll see the processes increase named "php-wss" as CPP (Connections Per-Process) will grow and decrease while stack will lessen.
 For instance, if set 100 CPP and there are 128 connections - You will be able to see 2 "php-wss" processes with for ex.: `ps aux | grep php-wss`
