I have one big Pl/Pgsql function (about 1500 line code) , i can divided it to about 5 part and call each script from main script . In this case i need to know which way is faster .
and some question about pgsql :
1- is pgsql engine open one process for each script ?
PostgreSQL uses one CPU per session.
2- how i can chose max connection number for pgsql server based on cpu core and RAM capacity that have maximum Efficiency?
usually max performance is about 10 x CPU connections. But it highly depends on load.
