Req #71854 [NEW]: FPM: Please make epoll sleep interval configurable

From: elrond+php dot net at samba-tng dot org Operating system: Linux PHP version: 5.6.19 Package: FPM related Bug Type: Feature/Change Request Bug description:FPM: Please make epoll sleep interval configurable Description: ------------ FPM in ondemand mode seems a perfect tool for a server/laptop that is running php very seldom. On a laptop every wakeup is important, because it will bring the CPU usually to nearly full power. Running FPM in this scenario wakes up the CPU every second. This sounds seldom for servers, but it's often on a laptop. strace shows this nicely: epoll_wait(10, {}, 1, 1000) = 0 The relevant code is in sapi/fpm/fpm/fpm_events.c, function fpm_event_loop(). Especially the "timeout = 1000;". It would be cool, if this would be configurable, so that one can set it to 100 sec for example. Expected result: ---------------- much longer sleep periods, if desired. Actual result: -------------- wakeup every second. -- Edit bug report at https://bugs.php.net/bug.php?id=71854&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71854&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71854&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71854&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71854&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71854&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71854&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71854&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71854&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71854&r=support Expected behavior: https://bugs.php.net/fix.php?id=71854&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71854&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71854&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71854&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71854&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71854&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71854&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71854&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71854&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71854&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71854&r=mysqlcfg
