[SR-Users] authentification issue when nb user increase

[Daniel-Constantin Mierla]

Hello,

is the database server using a lot of cpu? You can also try to set a
larger value for tcp_children global parameter -- note that for all
tcp/tls sockets, there is a single pool of processes, not per socket
like for udp.

Cheers,
Daniel
