Description: ------------ serialize use a lot of realloc which are very slow on FreeBSD >From - http://rgarciasuarez.free.fr/p5p/p5p-200307-1.pod - Dan Kogai explained that FreeBSD comes with an implementation of malloc() that is optimized for paged memory, and safe from duplicate free() calls. But the downside is that realloc() is very slow. That's usually not a big deal, because most programs don't use realloc() very often -- but perl does. (The default configuration of perl on FreeBSD is to use perl's internal malloc, that hasn't this realloc limitation.) Serialize use a fix incremental value (SMART_STR_PREALLOC in php_smart_ptr.h). It better for serialize to use exponential incremential value to reduce number of realloc. -- Edit bug report at http://bugs.php.net/?id=32727&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32727&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32727&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32727&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32727&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32727&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32727&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32727&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32727&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32727&r=support Expected behavior: http://bugs.php.net/fix.php?id=32727&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32727&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32727&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32727&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32727&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32727&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32727&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32727&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32727&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32727&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32727&r=mysqlcfg
