Hi,

We have about 500 hosts and we were testing the ssh connections that run in 
parallel at a given point before running the actual playbooks as we were 
hitting bottlenecks.

Ansible version being used: 2.10.5

Its a simple playbook which runs "ls" command on all the hosts.

QUERY 1:
-----------

Set the forks to 200 but i see the increment happening at max 64 ssh 
sessions/second using a watch command: (RAM 64 gb, 8 cores)

I was under the impression that Forks when set would indicate that many 
hosts the ssh connections would be created in parallel but thats not the 
case.

I should be seeing 200 ssh connection at once.

Can you please let me know if i am missing anything here? (pipelining, 
controlpath everything is set)


QUERY 2:
-------------
Also tried with the mitogen and non mitogen strategy and see the following:

*strategy: free*
Monday 18 October 2021  00:25:15 -0700 (0:00:05.505)       *0:00:17.968* 
******** 
=============================================================================== 

Run traffic from sources 
----------------------------------------------------------------------------------------------------------*--
 
5.51s*

Here it says plabook took 5.51 seconds but if you see the time above its 17 
minutes

*with Mitogen*

Monday 18 October 2021  00:26:29 -0700 (0:00:12.428)       *0:00:12.529* 
******** 
=============================================================================== 

Run traffic from sources 
-----------------------------------------------------------------------------------------------------------
 
*12.43s*
Here the time almost matches.

Why this discrepancies seen for strategy set time does not match? Any 
reason?
what time should be considered here?

Regards
Aprameya
