Hello. I have an issue with SOGo web performance, very slow performance on all pages(INBOX, Calendar), about 20 seconds waiting for response. I have ~300 clients which uses SOGo web interface.
My VM configuration: 4CPU, 32GB Ram
I increase WOWorkersCount to 70
and SxVMemLimit to 384

Are there recommendations for config to increase SOGo web performance? Which WOWorkersCount must for 300 clients? Thanks for any help.

Please increase the prefork child processes in /etc/default/sogo on Debian/Ubuntu (and /etc/sysconfig/sogo on CentOS/Rocky/Alma), then restart sogo service.

WOWorkersCount in /etc/sogo/sogo.conf is not used on Linux.

Yes, I changed PREFORK in /etc/default/sogo too, but the problem is still there

Is CPU busy when SOGo is slow?

No, average CPU load < 10%

Re: SOGo slow performance

- Are other web applications slow at the same time? Or just SOGo?
- Any error in Nginx log files (/var/log/nginx/*.log)?
