I experienced this once myself with a system I started to administer, the old admin
tried to optimize with pconnect, and it brought the web site to a halt. Then I read
somewhere it was broke, and never used it again. The only reference I have is that a
search for "mysql_pconnect issues" yields 24000 hits, and "mysqli_pconnect issues"
2400. Of course most links are quite old.

Then I think the optimization achieved with pconnect is largely overestimated, and a
risk if you use temp tables. Very often you can optimize your DB connection much more
by using the local pipe instead of a local IP connection.

Sure, and you can base your choice on
http://de2.php.net/manual/en/mysqlinfo.api.choosing.php , but in a newsgroup you get
good advice, not only technical references.
