Hi all, my question:
What does mean the "S" of scalability for your SOGo installation?
or how do you evaluate it?
Thanks all to help me to consider the performance of my installation
Summary:
Version SOGo 1.3.9 / lightning 105 (Fresh updated)

hardware a bit special (cause of virtualisation : openvz)
virtualiszation          openvz / centos
memory                  6 to 12 Go RAM
processor                dual core@1,7GHz
harddrive                SAS 15KRPM

we just upgrade the contener from 6 to 8 Go RAM,(more if necessary)
same for processor upgrade from 1 to 3 VCPUs
operating system: debian 6 mostly up-to-date

Primary usage:
Nb potentials users: 3000 (students) only through the webmail (http) 
interface
Secundary usage: (cause it really works fine)
~50 of 150 potentials sogo-connectors with thunderbird
~20 iPhone to synchronise agenda https://domain/users/dav/:443

mail server: cyrus imap
authentification: openldap

How could I measure/check some point level of scalabity?
Is there any way, maybe already integrated tool?
number of sogoworkers considering availability of RAM (6-8-10 Go)
postgresql input output

I'm a bit in the fog! cause we reach since Setpember an unknowned 
maximum of users this year (+10%)
and even we try to anticipate the needs... it "seems" to be not enough.

If you consider there is a much better way to collect this sort of 
information to help me and the community of sogo users
please fill free to purpose!

I've collect few informations i wish share with the lists:
- RAM capacities regarding number of SOGo Workers : not more than ~4Go 
for not more than ~15 SOGo workers
- using log result of "sogo debug request" command line (showing time 
responding with reason)
I haven't found much more details on that, but i'm interesting in it 
more explanation.

The SOGoDebugRequest is set to YES;
so now i'm reading the log file per day with glogg.
It there a specific tool to explore sogo logs?

maybe it include in the sogo webmin modules?

in the 500000 to 750000 lines, I notice : successful login ~ 3500 to 
4500 lines per day
is it a good thing to measure the user load towards others installations?
Any records  are wellcome!
