In a non-threaded environment, your choices are the two classic/ ancient models: original CGI (one connection per hit) and original LAMP (one persistent connection per process). > if I have (say) 100 mpm-prefork workers, and 0.001% > of my queries are to the <Location> concerned (this ratio is approximately > correct numerically), I don't really want 100 database connections > constantly open, lasting for the life of the mpm-prefork worker. Then you want the classic-CGI-style setup. DBD will give you that with min=0, max=1, and no keepalive on the connections. Most people don't want that setup, because opening and closing database connections is too much overhead. But with prefork and your numbers it makes sense. Though a threaded MPM and a small number of persistent connections would be ideal! > Or can it pool connections between mpm-prefork workers?
