Emergency Reboot - Meltdown/Spectre Patch


Recommended Posts

Aqui fica um teste que penso ser o exemplo perfeito para ter uma ideia do impacto no nosso. Foi feito a um servidor que esta´a correr um site com Xenforo, como tal um ambiente similar ao nosso que é Invision.

  • OVH MC-32 Intel Core i7 4790K
  • 32GB Memory
  • 2x240GB SSD
  • 250Mbit Network Bandwidth
  • CentOS 7.4 64bit
  • Centmin Mod 123.09beta01 LEMP stack - Nginx 1.13.8, MariaDB 10.1.30 MySQL, PHP 7.2.1
  • BHS, Canada

Mesmo versão do Centos, do Nginx e do PHP. No MariaDB estamos a usar a versão 10.2.12.




  • Performance impact for my Siege benchmark results on CentOS with Intel i7 4790K was around 5.5% average of 5 runs for request rate and for longest transaction time around ~4.08%

Num sistema muito similar ao nosso, a perda de performance é expectável na casa dos 4% aos 5,5%.
