@plegrand
Everything seems work fine and i’ve no more error in log files.

@george1421

I had to modify this file :
/etc/php/7.3/fpm/pool.d/www.conf

;listen = /run/php/php7.3-fpm.sock
listen = 127.0.0.1:9000

Now it seems to work.

I’ve always these errors :

@george1421
Then i made some tests

Multicast session (test) with 2 target computers : about 1.7GB/min rate

Multicast session (test) with 3 target computers : about 1.7GB/min rate

Multicast session (test) with 4 target computers
The 2 first target computers didn’t start i cant understand why.
then i removed these to computers from the session (test)
i create a new multicast session (test2) for these 2 computers

Then there is 2 sessions running (test and test2) and all the target computers have about 1.15GB/min rate

All the computers have 2 partitions and strangely the first partition is slower than the second : about 700MB/min rate

@george1421 said in Multicast very slow:

Under a multicast you should get just slightly less than unicast speeds.

So what’s the multicast interest if it’s not faster, apart from not flooding the network?

I’m going to make some tests this morning with 2, 3, 4 target computers.
I will tell you the result

@george1421
The 6450 has all his ports 10/100/1000
not the 6250 only the uplink ports are on 1000

@george1421 said in Multicast very slow:

Do you have the capabilities to run a second network wire from the switch where the fog server is to the switch where the target computers are? (I’ll explain more if you can).

It’s quiet already the case
The switch (OS6250) where are connected all my target computers is just below the switch where the fog server is (OS6450).
And directly connected by a 1GB link
Then, only target computers are on a 100MB link
