I've read that. ;-) Done that I assumed that the value of PREFORK is the starting number of processes spawning additional processes until WOWorkersCount is reached. But it's clear now. Perhaps change the phrasing in 5.3? Greetings -- R. Cirksena -- users@sogo.nu https://inverse.ca/sogo/lists

Re: [SOGo] WOWorkersCount
Hi Ralf, on Debian and derived distributions (and maybe other distributions with similar mechanics in the init scripts), the `WOWorkersCount` option is overwritten by `/etc/defaults/sogo`'s `PREFORK` option. So `WOWorkersCount` is not used at all. `PREFORK` is actually a little bit misleading here, as it is not a prefork value as for other server systems where additional processes to the ones in use are forked, but instead SOGo's `PREFORK` starts (and maintains) exactly this number of processes, no matter whether they're required (or sufficient).

What is the recommended value to use in production (50 user, dual core Processor, 4GB of RAM). At the moment I have set it to 10 with no bad effects. Does anybody have recommendations? Should we but in more RAM or Cores (it is a VM anyway)? It depends on the value of SxVMemLimit. If it's set to say, 512, you could end up (but very unlikely to happen) with 10 processes slowly eating 512 MB of RAM - which would be too much for 4 GB. I have this model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz cpu cores : 4 with 4 GB of RAM. SxVMemLimit is default 384 With 30 users, how should i set WOWorkersCount? We generally use 10 when there are thousands of users so ±5 should be a more reasonable value for you ;) I understand that 1 child every 10 user is ok. With 30 user, should I set WOWorkersCount to 3? How can i calculate this parameter? Core, ram, number of users?
