Meltdown/Spectre patching and the performance impact


(ljpp) #1

The Meltdown/Spectre exploits have raised a lot of noise around the IT industry, and there has been a lot of comments regarding the potential negative performance impact of the necessary patches.

In our scenario, the performance and the maximum active user capacity of our hosting is limited by the CPU processing power. @mpalmer and others doing high volume Discourse hosting – have you observed whether the Meltdown/Spectre patches have the claimed negative performance impact in Discourse Docker environments? The media has used numbers like 5-30% and double digits would be rather devastating for us.
