This times I found inside the local LAN (1GBit-Switch and cable are OK).
Mailserver needs between 50…60% RAM and have 2 SSD (mirror) ,CPU 2x3GHz , DNS is OK
Is there anything I can do to perform faster ?
How can I delete user faxmaster (don’t need faxserver) ??
there the data you need:

… but the same performance:
After starting the nethserver6.8 the first 10 minutes good performance at sogo-webfrontend, but than it becomes slower and slower and it’s no fun to work. That’s the show INSIDE LOCAL NETWORK.
If I try to connect from outside it’s not very fast, but it’s better to work as inside the LAN.
Structure is:
Firewall IPFire with Green+Red+Blue+Orange
Nethserver in orange-LAN (DMZ)
DHCP/DNS-Server is Windows-Server2012
Is there any idea to find the brakes ???
Thanks for every tip …
thank you for the link Stephane.
But this is not logical. If I open sogo webinterface from outside (from home I mean), INBOX open needs ~3 seconds. But if I open the same INBOX inside the firm it needs ~10 seconds or more.
There is a firewall rule: red port 443 (https) > IPofNethserver (in orange). Thats OK and fast.
But the path from green to Nethserver (in orange) is much slower. The reason can’t be the sogo-config.
What to do ?
you can have also a side effect with sogo about java-script, if you want to do a test, you should use the same computer at home and at the firm. Indeed,now all the work to display the page is not on the server-side, but on the computer side (the principle of JS). Of course you might have a firewall Issue, let’s go to investigate.
Thank you for your ideas, but I think this are not the reasons. Here there is an excerpt of the sogo.log.
IS THIS NORMAL or is there an error in sogo-sync ??
Sorry the copy-paste eliminates the carriage return … and there are long-long lines
and sogo-direct (users@sogo.nu)- is not to handle for me, I’m too silly…
try again …
Hallo,
've running SOgo 2.3.10 on Nethserver 6.9.
Mailserver in DMZ of iPFire-Firewall
13 Users - 3 in office - 10 outside with smartphones (iPhone, iPad, Blackberry, Android)
.
Sometimes the time of reaction is very slow - especially in office(?! the green LAN) :
Login Sogo ~ 10…60 sec.
Open INBOX ~ 10…120 sec,
Open a mail: 5…180 sec.
But sometimes - most in the evening - it’s "normal fast"
I tried:
Mailserver in GREEN LAN > same problem
Clamavd stop > same
Testing DNS, traceroute > no errors found
time sync… OK
But found in sogo.log every second many [ERROR] and sleeping 5/10 seconds.
Is this “normally” ?
What should I do ?

Thank you, alefattorini ,
… it’s a miracle … yesterday I found in internet a way to improve performance
vim /etc/sysconfig/sogo PREFORK=10 USER=sogo
vim /etc/rc.d/init.d/sogod PREFORK=10
This changed the WOWorkersCount to 10
Now there are no more “[ERROR]…No child available to handle incoming request!” in sogo.log
Only many “Sleeping 10/5 seconds”
Now it’s fast enough. But I will wait a week to look again…
I will watch the RAM-usage
at 08:00 2711MB 00 swap
at 12:50 3201MB 00 swap
I don’t hope, that the next update re-change my improvement …
i think, the reason for slow performance are 10…12 smartphones in PUSH-mode.
After that, I will set to SOLVED (with a long way…)
Till next time …
thanks to stephdl ! Your tip solved my problem. Now sogo-webfrontend is really fast. And the best of all - after update-installation the sogo-config is the same as before.
I watched the system some weeks and it’s OK. The RAM-usage climbed from 2000 MB to 3500MB.
But after full-backup it climbed to 5000 MB + 41MB swap - machine with 8GB!. System don’t clear the RAM-usage - but this is another topic …
