I want to use my Raspberry Pi 3B as web server but response times are very different and unstable , many of them are around 80ms to 160 ms but some of them go to 5000 ms to 20,000 ms !
OS : Linux raspberrypi 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l WebServer : nginx/1.6.2 2017-04-20 12:44 PHP : 5.6.30-0+deb8u1 Opcache Enabled and it hits 100% of request after first request. Opcache have Enough Memory. opcache.max_accelerated_files = 20000 PHP Framework : Yii2 Basic Query time : 4 ms and its Stable. Yii Cache : ApcCache I request raspberry over Lan with 2 ms stable latency. CPU usage wont even go to 10%. IOTop shows 500KB write with each Request , i dont think it will be a problem.
