Bug #73757 [NEW]: Slow connection when using localhost as DSN

From: binarskugga at gmail dot com Operating system: Windows PHP version: 7.1.0 Package: PDO MySQL Bug Type: Bug Bug description:Slow connection when using localhost as DSN Description: ------------ --- From manual page: http://www.php.net/pdo.construct --- When connecting to PDO using the DSN, it is painfully slow on local if you're using "localhost". This can be fixed by using 127.0.0.1 at the moment. Test script: --------------- <?php try { $pdo = new PDO(mysql:dbname=foo;host=localhost;port=3306", $config["SQL"]["USER"], $config["SQL"]["PASSWORD"]); } catch(PDOException $exception) { die("Couldn't access SQL engine. (" . $exception->getMessage() . ")"); } ?> -- Edit bug report at https://bugs.php.net/bug.php?id=73757&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73757&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73757&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73757&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73757&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73757&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73757&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73757&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73757&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73757&r=support Expected behavior: https://bugs.php.net/fix.php?id=73757&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73757&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73757&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73757&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73757&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73757&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73757&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73757&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73757&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73757&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73757&r=mysqlcfg
