@george1421
obviously i’m not sure i did the right hoses
but i haded
KERNEL ARGS nvme_core.default_ps_max_latency_us=0
and haded postinit.script in the image section = nvme set-feature -f 0x0c -v=0 /dev/nvme0

i’ll try tomorrow the all process debug mode

thank’s

@Tom-Elliott
Agree with you !
i’ll get back to you very fast
but for now, i’ve created a samba share and i get full speed of what a gigabit nic can give so arround 112-120 mb/s
with acronis.

FOG 1.5.7.99

@Sebastian-Roth
After analysing the situation, here are my conclusion
i did add your code : nothing change
same slow ridiculous speed
maybe your not looking at the right place for the bug ! of slowness
we use FOG for more than 3 years, alway the same SSD and Same Machine, closely.
so conclusion, has nothing to do with nvme_core.default_ps_max_latency_us=0
nothing has change in our environnement except we upgrade fog every 1-2 mounth.

thank’s

@Sebastian-Roth
Found it ! soory
KERNEL ARGS

@Sebastian-Roth said in Very Slow:

i’m not sure exacly where to put the code ??
Thank’s

@Sebastian-Roth
You are currently running version: 1.5.7.96
bzImage Version: 4.19.64
bzImage32 Version: 4.19.64

ill try your nvme_core.default_ps_max_latency_us=0
in the kernel

@Tom-Elliott
server and node are lenovo P300
16 gig of ram

@Tom-Elliott
We restart !
of course !

the context is simple
since last mounth upgrade ! everything is kind of dead meat !
We test brand new router (corei5 4th gen 8gig ssd evo PFSENSE)
we test with 1 pc and 1 server - brand new switch
same problem !
the only difference since last update i notice is the fact that the database create a new secure user for the node because the user fogproject was not secure enought ! maybe it’s a coiincidence. but that’s the only factor that differ from all update done over the years.

do you need log ?? someting to help ?

Hello,
Debian Buster, Latest fog
ZFS on Root
SAMSUNG PRO 1 TB mirror

Last mounth, fog was gong arround 12-14 GB/min and thise was the average bitrate for the last years.
since last mounth, the bitrate has lower to 1-3 GB/min

SSD are like 3 mounth old
What’s the problem ??
Can you explain ?
thank’s
