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).

[SOGo] WOWorkersCount
Hi, I am somewhat confused re. "WOWorkersCount" / "PREFORK". If I set PREFORK = 3 in /etc/default/sogo with WOWorkersCount = 60 in sogo.conf just 3 children of sogod are started. That remains on this number even if users begin to use sogod. The only result is lng time waiting for synchronization. If I set PREFORK higher (10) then performance remains o.k. until all workers are busy. Workers don't increase above PREFORK thus never reaches a value near WOWorkersCount. Something is wrong. Clarification needed. ;-) Greetings -- R. Cirksena -- users@sogo.nu https://inverse.ca/sogo/lists
