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 :

I’ve got a lot of these errors in error.log :

@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

@george1421 For these tests for the moment i’ve no time enough but i’ll do these tests in a near futur

@george1421
I’m not sure to well understand
Actually my diagram is not “really” true.
The fog server is on a GB port
All desktop clients are on 100 M ports
I cant do anything else, no enough GB ports

@george1421
With a target computer far from the fog server it seems to works also

@george1421
To answer to your last question it was a session with 15 target computer and theses target computer was very near the fog server, on my drawing it’s the swith just below the fog server

@george1421

With only one computer it seams to works fine.

Image menu

Start Multicast Session

@george1421 Sorry but where is this “Start Multicast session” ?

@george1421 How can i make multicast on 1 computer? I can’t see this option

@george1421
unicast : 30minutes for 14 Computers
multicast : 24hours for the same computers

For information i’ve got these kinds of logs :
http://plegrand1.free.fr/multicast.log.udpcast.6

unicast works fine

@Sebastian-Roth
Hello Sebastian and thanks for your answer.
I made these tests (sorry for the french words) :

For me it works fine. What do you think about that?

Hello,
i’m trying multicast with fog 1.5.5 and alcatel switchs (OS6250 and OS6450).
When i launch a multicast session it’s extremely slow.
For the configuration of the switchs i made like this :

On all switchs enable igmp globaly and on vlan 2 (fog server)

ip multicast status enable
ip multicast vlan 2 status enable
ip multicast zapping enable
ip multicast vlan 2 zapping enable
ip multicast version 3
ip multicast vlan 2 version 3
ip multicast querier-forwarding enable
ip multicast vlan 2 querier-forwarding enable

On the querier switch (the closest to the fog server)

ip multicast querying enable
ip multicast vlan 2 querying enable
ip interface Querier address 192.168.39.244 mask 255.255.255.0 vlan 2

Disable igmp on all other vlans on all the switchs

All computers are on 100M port and the fog server on 1G port

You can see on this diagram http://plegrand1.free.fr/IGMP.png (old diagram )
not a ghost server but a fog server
I add global statement
The server is on a 1G port

the flow is very fast at the beginning then goes down to be very slow (25M / min)
Here is the server characteristics

PowerEdge T310
Intel(R) Xeon(R) CPU X3480 @ 3.07GHz
cores	      =	4
enabledcores  =	4
threads       =	8
Ram           = 32GiB

Ethernet interface
NetXtreme II BCM5716 Gigabit Ethernet
eth0
1Gbit/s

Could you help me to solve this problem ?
