I have been experiencing trouble setting SOGo so that its operation is not so slow, we currently have almost 1,400 email accounts working and being authenticated against Active Directory working properly via Dovecot IMAP or POP3 both mail clients (Outlook, Thunderbird, etc .) as with Roundcube via web.
I installed SOGo, so customers can synchronize mobile devices with your calendar and contacts, it is configured to use LDAP.
Until here all goes well, the problem has begun to notice now required that mobile users use ActiveSync, the connection to the server is slow and sometimes even zero.
In reviewing /var/log/sogo/sogo.log, basically this is the most recurring error:

Looking for a solution and reading in various forums, including the installation guide SOGo; I found that you have to adjust the parameters in the /etc/sysconfig/sogo Prefork =
On the advice of the guide settings I configured the PREFORK = 120 for the number of mailboxes that are handled (> 1200 and nearly 100 EAS)
Additionally, within /etc/sogo/sogo.conf, I added the following configurations:
WOWorkersCount = 120;
SOGoMaximumPingInterval = 3540;
SOGoMaximumSyncInterval = 3540;
SOGoInternalSyncInterval = 60;
WOWatchDogRequestTimeout = 60;
But when restart the sogo service and check the processes running only shows the following:
[root@genos ~]# ps aux | grep sogo
sogo 3616 0.1 0.8 336972 32464 ? Ss 18:29 0:08 /usr/sbin/sogod -WOWorkersCount 3 -WOPidFile /var/run/sogo/sogo.pid -WOLogFile /var/log/sogo/sogo.log

root 16212 0.0 0.0 103340 868 pts/2 S+ 19:42 0:00 grep sogo
Additionally within /etc/httpd/conf.d/SOGo.conf, settings for ActiveSync is:
ProxyPass / Microsoft-Server-ActiveSync \
http://127.0.0.1:20000/SOGo/Microsoft-Server-ActiveSync \
retry = 60 ConnectionTimeout = 5 timeout = 3600
ProxyPass / SOGo http://127.0.0.1:20000/SOGo retry = 0
And SOGo still very slow.
Server hardware has a Xeon 8 cores and 16GB of RAM, and the operating system is updated. I do not know if I'm missing something or some of the parameters is wrong, because SOGo works but too slow.
I appreciate any help
