Req #78610 [NEW]: AMD CPU Performance (help!!!!!)

From: celestinoxp at hotmail dot com Operating system: Windows 10 PHP version: master-Git-2019-09-29 (snap) Package: Unknown/Other Function Bug Type: Feature/Change Request Bug description:AMD CPU Performance (help!!!!!) Description: ------------ I recently bought a new laptop and after some testing I think something is not doing well. I think it might be better considering it's a new and powerful laptop. I have a php algorithm with mysql that does a lot of checks on the database, as well as a lot of checks on multiple arrays and found that only 1 cpu core is being used, I find it a bit odd to keep in mind that the CPU is very powerful and I am not enjoying all the CPU capacity. Laptop specifications are: - Laptop: HUAWEI MateBook D (14 AMD). - AMD Ryzen 5 (2500U) 2.00GHz - 3.6GHz CPU (with Radeon Vega Mobile Gfx). - RAM: 8 GB. - Storage SSD 250GB. To investigate better benchmarking possibilities, I thought it best to use this algorithm: https://github.com/zendtech/julia It is ridiculous to see that the processor is working at about 25%, with only 1 of 8 threads at 80% + / - and the other 7 threads almost stopped. The above script has a performance of about 3.2FPS. Question: Am I asking this question in the right place (PHP DEV) or should I contact AMD? What should I do? And who should I contact? Test script: --------------- https://github.com/zendtech/julia Actual result: -------------- FPS 3.2 -- Edit bug report at https://bugs.php.net/bug.php?id=78610&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78610&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78610&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78610&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78610&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78610&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78610&r=support Expected behavior: https://bugs.php.net/fix.php?id=78610&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78610&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78610&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78610&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78610&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78610&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78610&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78610&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78610&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78610&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78610&r=mysqlcfg
