Hi everybody, We have done some very tentative measurements on the Linux Meltdown workaround & impact on DNS performance.
Based on very early measurements we see around a 10% impact in queries per second for a UDP heavy workload. In addition, one largescale user of PowerDNS Authoritative Server on PostgreSQL suspects the performance problems they see coincided with the rollout of Meltdown workarounds, but we're still investigating. Finally, we did a writeup what Meltdown and specifically Spectre actually are, which you can find on https://ds9a.nl/articles/posts/spectre-meltdown/ We will keep you posted as we learn more!
