Should we also move to multi-process mode for uwsgi @maxking ?

@danil-smirnov yeah, I think we can safely bump the number of processes now.

[danil-smirnov]

@maxking I'm not sure what processes/threads configuration is reasonable actually... I didn't hit any issue with the 1/2 setup. Do we really need to use multiple processes here?...

[maxking]

It really depends on how much traffic do you get on your webserver. I think 2 workers with 2 threads each should suffice for most people. It might be good to have 2 workers to take advantage of 2 Cores and then spin off 2 threads each (threads are much cheaper resources wise, compared to workers) so we have some headroom for high traffic times.

Then let's apply it @maxking :)
#470

[danil-smirnov]

I wonder if Postorius image should have the same configuration @maxking ?
The current four processes look a bit overkill to me...

[maxking]

We can probably do the same with Postorius, its not that much of an overhead.

[danil-smirnov]

@maxking Then this is it: #472
