Have a code:
$profiler->enterSection(‘MDB2connect’);
$mdb2 =& MDB2::connect("mysql://$mysqllogin:$mysqlpass@localhost/$mysqldb");
$profiler->leaveSection(‘MDB2connect’);
and then in result i see
total ex. time netto ex. time #calls % calls callers
MDB2connect 2.6473159790039 2.6473159790039 1 N/A Global (1)
Why the MDB2 connect can be so slow ?
